Your information is very well received. I may have significant information on your Uhlfelder family which I will try to put in an email to you this weekend. The family record which I pieced together goes back to the village of Uhlfeld where my file ends with Hirsch Marx Uhlfelder born circa 1735. The birth and death dates of Samuel are at some variance but everything else fits well. In the meantime, please let me know if you have any better dates for his birth and death.
I have been trying to connect this family with my line which was in Erlangen and Dormitz, Bavaria.
