Joseph Inscho SR.; Susan Inscho; Edward Oscar Thomas

I am descended from Samuel Inscho, older brother of Obidiah and Joseph Inscho, Jr. I have some info on their descendents and I am showing their father as Joseph Inscho, Sr. born about 1733 and died after 1760 in New Jersey USA. So far I only show these three brothers. I am interested in verifying Joseph Inscho, Sr. and even finding his ancestry. My tie-in to the Inscho family is Susan Inscho married to Edward Oscar Thomas IV, Susan was daughter of William Earl Inscho (1826-1889) and Abby Ann Croyle (1832-1918). William lived and died ( Flood )in Johnstown Pa.
