I'm unaware of a John Gaston born 1809. My direct ancestor is Justice John Gaston born in Ireland but came to America as a young man. Married in Pennsylvania where all but one of his children was born. Became Justice to the crown and moved to South Carolina about 1762. His son John born in 1745 married Janet Knox and their daughter Ester Gaston married a cousin Samuel Gaston the son of William Gaston and Mary McClure. Samuel and William were friends as well as relatives. They married in South Carolina but moved to Notherwest Territory about 1806 when Esters father died. They took Janet with them. The area was known as the Indiana Territory until it was divided into states. Later it was known as Marion County, Illinois.
So many named their sons John I can't say which one had a son John born in 1809. I do know that the Revolutionary War families were all born in the U.S. in New Jersey or Pennsylvania. Joseph Gaston of New Jersey is a relative of Justice John, he could be a brother since I read in a book that Joseph's son refers to Justice John as an Uncle. This information is in a book.
This is the information I've collected on Joseph's family.
An older Joseph Gaston was a possible Brother of Justice John.
