Amy - this Chrisitan N.. was born ca. 1775 d.1 July 1831 ( his will is dated 1828.he married Barbara Supinger about 1775 and they had 8 children, including Susannah b. 1785 ( she married John Scott). last child, Mary b. 1798 and since wife Barbara is not listed in his will I assume she died betwee 1798 and 1832.I think that Christian's father was John Jacob Niswanger b abt 1701 d. 1754 in VA,who came to PA between 1711 - 1719 with his father and a brother named Christian.There is some debate whether your Christian is the son of John Jacob ( which I favor) or of brother Christian.In any case, John Jacob married Maria Brumbach in 1738 and I think that your Christian was one of their 4 children.
