Jack, My 3rd Great Grandparents went to Gratiot County in the late 1880's for religous reasons. Specifically for the Church Of God to help establish "camp meetings".They were in St. Louis, Mi.
I have a book in my posession that is titled "Laughter Among The Trumpets" and it is the story of the Church Of God in Michigan. I know this post is about your Woodmansee line, but the reason that I am telling you about it is because there is a section in the book about a Leroy Sheldon, who was bornMay 23, 1854. The book also includes a few photos with him it.
If you are interested in this information, I would be happy to transcribe this section for you in an email. I could also scan the photos of him.
I just thought I'd ask, in case he was someone that you are interested in and may be unaware of this book.
