Recently we created a new tree on Ancestry, as searching by "Smith" was not giving us many good results. We have reason to believe the Smith family may have been Schmidt, so the new tree is very small, but narrows down the family a little, and the different surname has given us a few new leads.
In addition, we have posted Dad's DNA data in Ancestry's DNA database, and we're now waiting to see if we'll see any solid matches in the future. At this time, there are a few matches, but nothing clear enough to pursue as close family members.
Somehow in all of this, we hope to make some headway with the Smith/Schmidt family. The new church records from Pennsylvania have given us some hope, and with a little persistence, perhaps we'll get some proof of the family's arrival in North America, and clues as to where in Switzerland they came from.
