Mr. Emigh: I just noticed that I neglected to respond to your question about "Ezekiel" Emigh. This name should have been Isaac Emigh, brother of William who was born in 1800. At the moment I don't not recall where I got Isaac's name. We have no additional information on him.
I came across some interesting information re: Emigh Family in the Ingersoll Chronicle Online Database, birth marriage and death notices published in that paper. There were 11 matches for Emigh going back as far as 1878. You may already be aware of this resource.
