Jacob Kooser was born 17 Nov 1754 in Berks Co PA, son of Hans Michael Kooser and his wife Anna Maria Sybilla.He died in Lavansville, Somerset Co PA, between 1 Dec 1794, the date he signed his will, and 5 Nov 1795, when the will was proved. He was buried in Samuel’s Churchyard, Lavansville PA.
He was married in 1785 in Colebrookdale, Berks Co PA, to Mary Sample. Mary was born about 1758, possibly in England or Delaware, and died after 29 Aug 1813 in Lavansville PA.
There was a John Sample in the same section of Bedford Co PA in 1790, and a George Sample in Milford Twp, Somerset Co in 1800. Three “Semple” men also witnessed her husband’s will.
Thomas M Koser writes: “Since three men by the name of Semple or Sample witnessed the will of Jacob Kooser, it is understandable why descendants are of the opinion that Jacob’s wife was a born Semple. However, there is some evidence pointing to the fact she may have been the daughter of Joseph Anthony, a merchant of Philadelphia. (This could be cleared by checking the Will of Joseph Anthony in Philadelphia Courthouse).”
Not so. I obtained Joseph Anthony’s estate and no reference is made to any relatives or to land in Somerset Co. (Note that for $28, which was a large genealogy expense for me at the time, the courthouse said they would send the will, but they sent the estate papers, not a will.) The biography of Joseph Shultz in Lee Co IL History states that his grandmother was Mary Sample, that she came from England to Delaware to PA, and that she lived to the age of 83, that is, ca 1844, given a possible birthdate a few years younger than her husband, and within the adult memory of Joseph Shultz.
During the Revolutionary War, Jacob Kooser served in Capt Stephen Crumrine’s Berks Co PA Company of Militia.
Sometime after his father’s death in 1774, Jacob moved to Bedford Co PA, the part which later became Somerset Co PA. Jacob executed a deed in Berks Co PA when he moved west, 1794. He was also mentioned by name in a sister’s will. His brother also moved to Somerset Co. Both men were in Milford Twp, Bedford Co in 1790. Bedford Co PA, p 24. Jacob Kiser: 1/0/1. The widow, Mary Kooser, was on a 1796 tax list in Milford Township. Her 1800 census shows all four children living at home: Somerset Co PA, Somerset Twp. Polly Kyser: 11001/11010/00. In 1810, she was probably with her daughter, Catherine Shultz’s family: Somerset Co PA, p 369, Conrad Shultz: 11010/21201.

 Baptized 20 Apr 1755, Jacob Bauman and wife were sponsors. He was confirmed 1 May 1774 (17 years old, the late Michael’s son), New Hanover Lutheran Church, Falkner’s Swamp, Montgomery Co PA. It has been suggested that Jacob’s mother was a Bauman, that is, a relative of the baptismal sponsors of her child.
