Shelden was the son of my Mary Anderson ancestor. I have allot of this data and can get it for you if you email me at email@example.com.
Did you ever get a copy of The Winterrowd/Winterrow/Winterroth book? It was written by Vern Carpenter.
Vern Carpenter passed away a few years ago. Erik Conard assisted with the book and loaned me his copy a few years ago. You can find Erik's email address at the Genforum.com "Schnorf" family page.
Also, I believe that I found a copy at a library/historical society in either Shelbyville In,, Indianapolis In. If it's at aPublic Library you can find out at your local Library and have it shipped to you for free to review for two weeks.
You may want to contact folks at the Shelby county, In. rootsweb.com site for this book.
