Susannah, george, hans georg Nye "Nigh"

I am looking for info on Susannah Nye "Nigh" b.1783 in Maryland who married John Neff b.1777 in Penn. They had a son named Samuel J Neff b.1820 in Ohio.
Susannah's parents were George Nye "Nigh" b.1755 in Penn. and Mary Magdelena Saylor b.1757 in Maryland. George's parents may have been Hans Georg b.1713 in Prussia and Maria Elisabeth Horpuff b.1713 in Prussia.
Hans Georg's parents may have been Hans or Johann Cristoph Nye "Nigh" b.1683 in Prussia and Anna Catharina Jung. Johann Cristoph's parents may have been Sebastian Nye? and Magdalena?
Any help with this family would be very very helpful!!!!!!!!!!!!!!
