The problem is the connection between the elder Adam (b. ca. 1690) and Jacob (b. 8 Nov 1724).DNA has proven that this Jacob is the son of Johann Pieter STRAUB I, the 1733 immigrant to Philadelphia, not s/o Adam, s/o Mathias.
If the birth date you show for Jacob STROUP is correct, the connection is emphasized because that means he's a twin to Johann Pieter STRAUB II, whom we know from his tombstone in St. Peter's Cemetery, Freeburg, Snyder Co., PA, was also born on 8 Nov 1724.
Yes, I noticed you joined the project.I'm so pleased!The other descendant of Adam3 (Jacob2, Johann Pieter1) will also be pleased.I'm about to make an announcement on the STRAUB-DNA mailing list, to which I would welcome you to subscribe:
