About This Site

This is a family archive documenting the ancestry of the Krumpos, Schmidt, Martin, Coppersmith, and allied families of northeastern Wisconsin. It traces lines back through ten countries and over four centuries, from Pierre Desportes in 1588 Normandy to present-day Green Bay.

What's here

Individual profiles for 173 documented ancestors, organized by surname. Each profile includes birth and death dates, family relationships (with clickable links where records exist), biographical summaries, source citations, and research notes.

Beyond the individual profiles, you'll find a narrative history tracing every line from the Old Countries through immigration to Wisconsin, surname origins showing how names evolved across borders, and cross-cutting patterns like extraordinary longevity, synchronized deaths, and geographic clustering.

Privacy

Only deceased ancestors are included. No living relatives appear on this site. If you believe any information here is incorrect or should be removed, please contact Don Krumpos.

Contribute a memory

If you knew any of the people documented here — a story, a memory, a photo, a correction — we'd love to hear from you. Every person's page has a "Remember something?" form at the bottom. Submissions are reviewed before being added to the site.

Information comes from census records, obituaries, cemetery records, marriage certificates, WikiTree profiles, the Little Chute Genealogy Database, FamilySearch, and family oral history. Each profile cites its specific sources.
