I see two different spellings for Mary Priscilla's name. If its indeed spelled with an "h", I suspect that she would belong to the descent of Andreas Blocher (Immigrating nephew of my immigrant Matthias Blocher (1730-1803), considering that lineage is hugely based in Maryland. If the spelling is actually spelled with a 'k', then she most likely comes from Michael Blocker I, who settled in Alabama. Or she could come from Samuel Blocher & Catherine Morningstar (son of Mathias Blocher, whom changed the spelling of his name from BlocHer to BlocKer)but they would mostly be in Ohio. If Norman Hare Jr. is reading this, I would love to get his input!
