I just saw your message. I can add a little. He's my 3rd gr. grandfather. My line is:
J.A. W., Mary Polly Harriet Wyatt, 1828-1896, Sarene Sarah Irena Mitchell, 1849-1904, Joseph Marion Johnson, 1883-1965, George Harvey Johnson, 1919-2004, to me Pamela Dene Johnson (Whitney) 1950=. I just have bits of information on my line, but I'd be glad to share, and would love anything you have.
Let me know if you're still interested.
