I am trying to find the children of William Holder born Abt. 1792 & his 1st wife, Mary Watterson born 3/25/1789 who died sometime between 1830-1840. They lived in Sugarcreek Twp., Armstrong Co. PA. I know they had a daughter Susan born Abt. 1816 & I think Joseph born 1829-1830. William later married Prudence born Abt. 1805 before 1850. I am also trying to figure out who daughter, Susan married. Someone thought she married Robert Platt but all I can find is a Robert Platt born 1800-1810 living in Toby Twp., Armstrong Co.PA in 1840 with female age 20-25, 2 males under age 5 & 2 females age 5-10. Then in 1860 there is a Susan Platt age 44 a widow living with daughter Sarah E. Platt age 8 in Perry Twp; Clarion Co. PA. Here's hoping someone knows this family. Any help will be greatly appreciated. Thanks so much, Gloria Weiss
