In reviewing the pension file of Thomas Morenus of the American Revolution I found the following Bible entries for a William Swart and his wife Marilla/Marillus (Stible?) Swart of Oneonta, New York: (p. 28)
William Swart born 17 March 1771
Marillis Swart born 26 June 1778
Married: January 1795
Children: Betsy, b 26 Dec 1795; John b 6 Dec, 1798; Peter 3 Aug 1805; Nancy 7 Aug 1808; William Henry b 13 May 1813, Abraham 7 August 1817.
This family lived close to Thomas Morenus and Mary (Staley) Morenus in the Oneonta area. (merged from Milford to Davenport to Kortright to Oneonta).
