My Nay line coincides with the 1949 Nay Genealogy book (Ernest Omar Nay) with Jacob(1)-Samuel(2)-James(3)- Margaret(4)...
Some trees list our first Jacob b.1731, Trubach, N-S, Germany, arriving Philadelphis 1734, married Mary unknown about 1745, died 1828. Son Samuel, etc.
However this book has a photo of his tombstone reading: 1723-1828 and I see that birth date elsewhere.
Can someone clear up this date discrepancy?
