Shawn Family Genealogy Forum
I have not been able to find out where he was from. Frederick Homer (my grandfather) was born in Litchfield, Illinois. The LDS site shows George M. and Mary P. (Vineyard) Shawn as being married March 25, 1884 in Montgomery, Illinois. Some of my cousins have mentioned the Shawn Museum in Ohio. I have a note, dated April 12, 1957 that says Mary P. Shawn was born near Troy, IL, this information taken from a family Bible.
Hope this helps. I am still looking for more information and will keep your address handy in case I find anything.
