Hi, I am related to Nancy who is the wife of Cornelius Breece . Prior to her marriage she was living in the household of Edward and Mary Hobbs, listed as Nancy Hall 27 years, in the 1850 Onslow County census. She is shown there with two 4 year old boys who we believe were her twins.They were most likely born out of wedlock. One of them, Edward Jackson Hall, was my G grandfather.By the time the 1860 census rolls around she has left the boys and married to Cornelius Breece who I believe I am correct in saying, has lost his first wife and mother of his older children including the William you refer to.As far as his presence in the Martin household, I believe he was just working in order to live since his mother had died and his dad had remarried. I do not have any of the Breece family photos ,only those of my Hall side of this family. Hope this hlps a little , Steve
