I realize this is a little old, but, when I read your message, it was a breath of fresh air. I am looking for the exact same line. My GGGgrandfather was Benjamin Corbin, his Daughter was Missouri Iowa Corbin, she married Charles Henry Burtts, and had William Emmett Burtts, who had Edward John Edwards, my grandfather.
What did you learn about this line?
please email me.
