“THANK YOU NOTE”
“I would like to thank Dr. Kamila Klauzińska for conducting a two-hour genealogy training at the request of the Jewish Community Center of Krakow for Katarzyna Suszkiewicz on March 19, 2021.
Dr. Klauzińska presented extensive knowledge, both theoretical and practical from her own genealogical experience and research. She demonstrated the process of genealogical research, the selection of methods and means, contact with institutions with genealogical data, and methods of archiving the process. This knowledge will allow our employees to work with our clients more effectively and efficiently.”
– Jonathan Ornstein, Executive Director, JCC Krakow“They conduct thorough research.”
“We have known Petje and Kamila for many years and have found them to be diligent and effective researchers. They conduct thorough research for their clients and, from all we hear, have consistently made favorable impressions as guides as well. As colleagues, they have always shown their willingness to share their discoveries with others, a rare and generous trait.”
– The Emanuel Ringelblum, Jewish Historical Institute Jewish Genealogy & Family Heritage Center, Warsaw“Kamila is kind, caring and intelligent.”


“Kamila, her associates and her vast network of local contacts were just what I needed in researching my family’s roots in Poland. Kamila assisted me prior to my first trip to Poland, as well as during my visit. She knows people and was able to get the cooperation necessary to get the answers I was hoping to find. Kamila is kind, caring and intelligent. But most of all, she understands the importance of helping people make their personal connection to their past. I have and will continue to refer researchers to her.”

“Kamila caring for my ancestors’ cemetery and doing genealogical research for my family.”
“My name is Menachem Yehuda, the son of Moshe Yosef who the son of David who the son of Moshe Yosef who was the son of David who was the son of Shiya who was the son of Itzikel who was born in Kalisz, Poland in1755. Getting to know these ancestors through Kamila Klauzinska’s professional genealogical research has enriched my life. Growing up as the son of Holocaust survivors I missed knowing my grandparents, aunts, uncles and cousins who perished. I find in genealogy a way to reach over to a time before the Holocaust and reconnect to my relatives and ancestors. This yearning has also drawn me to many trips to Poland to search for what remains of over 1200 abandoned Jewish cemeteries where my ancestors and millions of other Jews still rest. My most memorable trip has been documented in my film Hiding and Seeking in which you can see Kamila caring for my ancestors’ cemetery and doing genealogical research for my family. In the film I meet older Poles who risked their lives to save Jews during the Holocaust. In Kamila I have discovered a Pole of the post-Holocaust generation who is dedicated to saving and honoring the memory of Polish Jews.”
- Dr Menachem Daum – filmmaker, NY, U.S.A.“I have had the privilege of hiring Petje Schroeder.”
“I have had the privilege of hiring Petje Schroeder as a personal researcher for my family research. Petje proved to be thorough, diligent, and innovative in finding records for my family going back to the late 1700’s. My maternal grandmother’s town had no records that survived WWI or WWII and it was a difficult task. But taking the family tree I had created she was able to find through her diligence that the family had previously lived in a town about 40 miles away and using the family tree and naming patterns was able to do much research on my family in the archives for the area. In addition to vital records, Petje was able to obtain items such as water charges, taxes, voters list, attestations and house owners and tenants. I recommend Petje Schroeder without hesitation for genealogical research in Poland.”

“They are the best assistance you will find in Poland.”
“If you need experienced researchers for your genealogical quest, I recommend Kamila Klauzinska and Petje Schröder. They are the best you can think of. I have known them for 10 years, I have worked with them, and I can testify that they provide the highest quality research about family roots in Poland. They have assisted me in various archives and USCs, found huge amounts of records and rare documents, explored cemeteries, translated texts, and much more. Kamila speaks French, English and Polish, read old Russian and can read Hebrew tombstones. Petje has excellent command of Polish, German, Russian, English, and Dutch (she is originally from the Netherlands).
"They are the best assistance you will find in Poland. Be in touch with them: you will not regret it!”
- Prof. Daniel Wagner, Weizmann Institute in Israel“Petje Schroeder was a pleasure to work with.”
“Petje Schroeder has conducted a large part of my private genealogical research. Although Petje is not Jewish, she has a good sense for Jewish naming patterns and customs. Not only did she find the records, but she put all of the information into EXCEL spreadsheets and she used the data to construct family trees. All of our communication took place via email. She was a pleasure to work with and we have kept in touch ever since.”
- Philip Freidenreich, January 2013“Petje has worked tirelessly for me.”
“I personally recommend Petje Schroeder as a researcher for Polish Jewish genealogy. Petje has worked tirelessly for me for at least 10 years and I would recommend nobody else. I currently have almost 3000 people on my maternal family tree and I can attribute at least 1000 of them to Petje's research.”
- Howard Lewin, Florida, U.S.A., February 2013
“Kamila will become your friend in a process that will enrich your life.”
“Dr. Klauzinska – she’s an author, scholar, researcher, and diligent digger. She connects people with their families and gently guides them to places where their loved ones lived, and where they died. Though she’s earned her doctorate at the most prestigious university in Eastern Europe, just call her Kamila, for she will become your friend in a process that will enrich your life. You think you will be asking her to search the archives and data bases for your loved ones. She will do that. She will uncover rich information that will help you piece together their stories so that they will become part of your own. But you will also receive something you didn’t expect, a surprise that may startle you, as it did me. I’m a Holocaust educator. I never thought I would want to step foot in Poland or identify with the culture or people there. There was an aversion. Kamila helped change all that. As I conducted research for a Jewish family with which I am connected, I kept discovering articles about Kamila’s work in the history of Jewish Poland or articles she had authored. When suddenly I found her contact information, I e‑mailed her and her response was immediate. She will no doubt do for you what she did for me, and for an entire university community in Illinois when we brought her there to speak. Kamila connected us with life, with the holy ground where Jewish people lived for one thousand years, and with a culture of Poles who are seeking after what we lost, and learning all they can about Israel and the Jewish people.

“Dear Kamila”
“I know that you are well aware of my story, nevertheless, I feel that without few words about it, my letter is incomplete. My father Shmuel-Yosef Sat was born in Zdunska-Wola, Poland. He Immigrated to Israel, where I was born. He passed away when I was three years old. Only a handful of his close relatives lived in Israel, when I began to probe about his family, none of them was left. I began to quest in the usual ways: books, the web etc. After a more than a year I was mainly frustrated. Luckily, at this point I met a friend who explained to me that Polish, which was not my language, is most essential for this matter, and that the researcher should deeply understand both: the culture of the Polish Jews and the procedures of the Polish bureaucracy. He advised me to contact Kamila Klauzinska who's living in Zdunska-Wola and had 2nd degree in Jewish Studies. Now, only three years later, I can mourn on the graves of my grandmother and grandfather and on the graves of my grand grandmother and grand grandfather, and on other six graves of my relatives, in the Jewish cemetery of Zdunska-Wola. Now, I know all my uncles and aunts (the brothers and sisters of my father) and my cousins, and other four branches of the family who lived in Zdunska-Wola. Now I know other branches of my family, which lived in Poland, in: Lodz, Szczercow, Wieruszow, Belchatow, Dzialoszin, Kalish and Sieradz, back going till my earliest known ancestors, five generations before myself. Now I can tell the story of our family to my four sons and ten grandchildren. This is a dream came true.”
- Eli Sat, Kibbutz Gadot
My parents, Holocaust survivors, emigrated to the US after the War. We lived in a part of the Bronx where other Holocaust survivors clustered together many of whom were, as my parents, from Zdunska Wola. Their friends were almost exclusively from Zdunska Wola or as they called each other “Woler”. There were the Dzalishinskys, Holenders, Herlings, Kureks, Schwarzes, Seigmans, and Ulezalkas. When they got together the main topic of conversation was the life they had in “Wola” before the War. The Woler street names became as familiar to me as the streets in my own Bronx neighborhood. Fast forward fifty plus years, my son suggested that we go visit Zdunska Wola my response was an immediate yes. We contacted Dr. Klauzinska and agreed to meet in Zdunska Wola. When we arrived she took us to the cemetery which she had previously mapped out and took us to the graves of my grandfather and grandmother. My son got to be at the grave of his ancestor for whom he is named. She then took us to the Zdunska Wola museum directed by her husband where she managed to assemble my familial residency cards. In that collection, we found the vital details of my great grandparents, grandparents, uncles and aunts as well as their exact addresses. The streets names were the ones that I remembered from my childhood. But the biggest discovery was the name of my brother who was killed by the Nazis. His name was never spoken of at home. My family became complete thanks to Kamila, Dr. Klauzinska.
Beni Warshawsky, Director (retired) Los Angeles County Metropolitan Transportation AuthorityMission Statement
Our mission is to provide high quality research on genealogy, as well as field tours for descendants of Polish Jews. For over 10 years we have been assisting individuals and families with Polish-Jewish roots, uncovering unknown aspects of their personal history and locating long-lost and sometimes unknown relatives. Our research experience is extensive, and we possess excellent command of several languages, and are familiar with many aspects of Polish and Polish-Jewish history, culture and customs. We often lecture about genealogy-related topics at international conferences and workshops, including in universities in Poland and abroad.
Our References
Being genealogical researchers for over 10 years has given us the unique opportunity to cooperate both with genealogists all over the world as well as with filmmakers, writers, and scientific institutions. From these contacts and meetings we have gained a great deal. We endeavor to use this knowledge and experience in our work. We therefore allow those who have trusted us and of whom we have learned a lot to speak.
Who We Are
We are a Polish-Dutch researching team. For both of us Jewish genealogy has become a passion. Since more than 10 years we have been solving riddles, i.e. deciphering handwritten Polish, German and Old-Russian vital records, which has been only possible thanks to our knowledge of these languages. We perform professional genealogical research of your families back to its roots in the 18th century, taking you so on an exceptional journey to the past.
