The Butler County Genealogical Society will host the webinar “Seven Immigration Methodologies, with Case Studies Across the Centuries” at 6:15 p.m. on Tuesday, June 17, at the Butler Area Public Library, 218 N. McKean St. in Butler, Pennsylvania.

This presentation introduces seven methodologies to effectively trace immigrant origins, illustrated with examples from the early 1600s to the early 1900s. Family historians face significant challenges tracing immigrant ancestors, because of changes in language, culture, family composition, given name, surname, country of residence and occupation.

David S. Ouimette, who currently works for Family Search, will lead the webinar.
