The Jacob Haymaker who married Mary Rugh in 1794 was born in York County, PA on 07 Feb 1771. He was baptized as John Jacob Heumacher on 17 Mar 1771 in the Christ Luthern Evangelical Church in York County. His parents were Jacob Haymaker (Heumacher) and Eva Meyers(?). Jacob (Jr.) died 21 Jan 1834 and is buried in Plum Twp., Allegheny County, PA. After his wife, Mary (Rugh), died, Jacob married a "widow" Barton about 1810. They had two children who died while very young. Jacob Haymaker (Sr.) left PA and located to Franklin Twp, Portage County, OH in 1805. Three other sons went with him, leaving Jacob (Jr.) as the only one in PA. This has led to a lot of confusion between the two Jacobs. Even the DAR records have Sr. confused with Jr. Jacob Jr. was to young to serve in the Revolutionary War, however he was a Private in Fenton's 5th Regiment of the Pennsylvania Militia during the War of 1812. Have more information, if interested.
