Christopher, My uncle, Preston Murdoch, was born in 1891 on the Mud Creek Farm near Bay Port in Huron County. His oldest son was Preston, Jr. If this is the Preston you are looking for, I have a rather extensive family tree going back to about 1680 in Scotland. If you are interested, I'd be glad to share. Incidentally, I show you as Jim and Kathleen's son. Is this correct or are you the next generation?
