John and Samuel both in same twp & Co. in 1790, I'm assuming they are brothers, however, it could be his father, Samuel Sr.

SAR says: private, Pa. Troops, Revolutionary War. pensioned. {maybe I have two different John mixed together.}
DAR says: John: b. 1759 ST; d. 23 Jul 1835 PA; m Lavinia Scott; Capt & PS from PA.

Jun 2007: David S. Christian says:"John W. Jordan, Librarian of the Historical Society of Pennsylvania says in his book "Genealogical and Personal History of the Allegheny Valley of Pennsylvania" on page 745 in Volume 2:
"Captain John Sloan, son of Samuel Sloan, was born in Scotland. He was young at the time of his parents' immigration to the colony of Virginia. He was gallant and faithful soldier in the war of the revolution and was captain of a company in a Virginia Regiment. After the close of hostilities he received a large land grant in Pennsylvania from the government, for services rendered in time of war. This land, which was located in Clarion County, he divided into farms for his sons."
