So far all the Blums of PA that I have traced have come from Germany - a small town named Guttenberg - there are four/five now existing and I have not narrowed down the exact one yet. Most born about 1830's.
Jacob Phillippina - ab 1800
Children: Johann - 1830, Henry - 1839, and
Frederick Augustus -1845. I think Matthias born in 1832 may also be a brother but I have yet to find a birth certificate for him. Census records: born in PA, MD, and Germany - they all differ. Sorry I can't help in your search. Keep LOOKING! - Jackie
