The Jacob Halfacre that you spoke of was the son of Jacob (Havacre) Halfacre born 1746 in Rien River Germany. They came from Germany in 1775. His mother was from Sweden.Her name was also Elizabeth born 1747. I don't have the file in front of me right now but I think the William you are talking about was the brother to Jacob Halfacre 3rd, which is the line I'm from. This family gets confusing with 3 Jacob Halfacres but we have been looking for a longe time now and think that we have finely got it down.
