I’m stuck like Chuck when it comes to this fella. Alexander Berryhill has long been purported to be the progenitor of all of the Berryhills in the United States. My grandmother has a document in her handwriting, probably early 1960s, that noted a Berryhill Reunion in Pennsylvania in 1931, and gave pretty much the party line that Alexander was Numero Uno: born as Hill in Scotland, married in London, moved to Ulster where he became a grower of berries, hence berry-Hill.
Even before I started online genealogy on Rootsweb, Alexander was already identified as the forefather. He is now on Geni (where his wife has a fantastical genealogy) and Ancestry.
The date and spouse I have on his profile came from said document. I have searched diligently for any documentary source for Alexander, including Family Search which has difficulty recognizing the surname in 1600s sources.
I’m beat! And desperate! At a total dead end! If anyone, ANYONE(!) can provide some assistance here, I’ll be forever in your debt.
