Hi Doug,
You don't give dates or parents of your Uncle Samual but it sounds as if you might be related to the family of Luke Teachman who went west in the 19th century. I suggest you check out the great Teachman site at
dirtdoc@basec.net for more info on this branch of the family. I do know more about my John Teachman family t(NJ/NY) than I did last Novemeber but my branch daughtered out with my great grandmother Annabelle b. 1879 in NY. Good luck
