• Notes

  If he is the son of George and Gracey Snead Coates, then he is likely to have 2 wives and other children. If so, he did not name the children of his first wife in his will below. Since his daughter Sarah was not born till 8 years after hried, it's likely he had other children by his second wife that died young. This looks to be his will. Name Martha Coats Role Executrix Will Date 11 Sep 1779 Will Proved Date 28 Jan 1780 Comments Coats, William. N. Liberties, Co. of Phila. Sadler. Sept 11, 1779. Jan 28, 1780. R.253. Wife: Martha. Child: Sarah. Cousin: Warwick Coats, Junr., Son of Warwick Coats. Sister: Rachel Hartley. Exec: Martha and Warwick Coats, Junr. Page R:253 William who died in Northern Liberties, in his will he names cousin Warwick Jr. Coates, son of Warwick Coats. Since all the other Williams in this branch of the family are spoken for, I am guessing that he is the son of John Sr. Coats to mm a 1st cousin to Warwick Coats, son of Warwick. Timing, place and relationship to Warwick fit these facts. His will transcription by Charlotte Coats Sierks follows: PA Will Book R, p. 329 #264 William Coate, of the Loures Keys of Northern Liberties, County of Penn, Sadler, wife Martha Coats daughter Sarah, attains to the age of eighteen years, sister Rachel Hartley, Warrick Coate as executor, signed Sept 11, 1779, witnesses Josh Caunias, Isaac Coats, Peter Thomas, probate Jan 28, 1780. If this is his will, then his son George likely died before the making of his will. It is complete conjecture on my part that the William Coats who married a Martha (Pricket) and his possible sister Mary Chinoth is the William who is the brother of John, Abraham, and Isaac. I base this theory on the following reasons. 1) Abraham also lived in Northern Liberties, a region in the city of Philadelphia. 2) Abraham had a brother William of the correct age to be this William. 3) William's wife Martha, lived in Northern Liberties according to his will.
