Present-day Blattner descendants from Kolin, Czech Republic are a close match with the Bacharach Y-DNA. There were also Bacharachs present in Kolin at the same time as the Blattners. We have not yet located any of those Bacharachs to test. This shows only the Y-chromosome descent from the oldest known ancestor to the descendant who has contributed DNA to the project. For more information about this family, see the family tree page.
