Claire Varrieur Butler

I am a family historian and professional genealogist specializing in Erie County, Pennsylvania. In addition to client research, I volunteer at the Erie County Historical Society Library & Archives as an archival processor, and I assist the library’s archivist in researching early pioneer families of Northwest Pennsylvania and Western New York. My personal research, spanning more than 30 years, is primarily in the area of French-Canadian and British research and I have extensive experience working with French Drouin records and English probate, land, and parish records.


I have a BA in Economics/Accounting from the College of the Holy Cross; I hold a Certificate in Genealogical Research from Boston University; and I am currently enrolled in the American Records Certificate program at the University of Toronto’s National Institute for Genealogical Studies.


I specialize in researching probate, deeds, and local town records in Northwest Pennsylvania, and compiling family histories. I love a good mystery and especially enjoy helping clients knock down long-standing brick walls. I am affiliated with several regional and national genealogical organizations, maintain memberships in several British historical societies, and have active subscriptions to premium records services with access to U.S., British, and French-Canadian records dating back to the 1600s. I’m also fascinated with the study of palaeography and enjoy transcribing early 16th, 17th, & 18th century British and American documents.


I am the editor of the Erie Society for Genealogical Research’s quarterly bulletin, and author of the blog
