Updating genealogy

I don't have my genealogy database with me on my laptop, but today I noticed at the Brethren Genealogy listserv that the FamilyHart database had been updated--524,488 people and 182,471 families. It is a Pennsylvania Dutch family, so I took a peek at the list of surnames. Yup. We're there. Well, not me personally, because only one of my grandfather's brothers (George d. 1944) is listed. But if you are related to any Shirks or Wengers, you'll find family there. My great grandmother, Nancy J. Wenger is (according the the FamilyHart DB) a 10th generation descendant of Hans SCHÜRCH. The Schurch family originated in Sumiswald, Bern, Switzerland. There are many spellings of the family name in America including Shirk, Sherk, Shoerg, Schrock. And a lot of Hans! I think I tracked Nancy back to Anna Burkhart Shirk, then sort of lost Anna in the mists of time. I think Anna married a Wenger and they had a son who immigrated. I'm not a real genealogist, I only have copies of a few wedding certificates, death notices and draft records. I rely on the kindness of strangers who do the heavy lifting.
