Good evening. I have a Mercy "Mattie" Clarissa MAXSON in my records married to John Simons HAMMOND April 26, 1855 in Poygan, Winnebago County, Wisconsin. She was born 1828 in Ohio to Jonathan MAXSON 1800-1880 and Namcy Alice FELTON 1800-1888. Both Jonathan and Nancy died in Lodi, Clay Co., South Dakota.
Mattie had several siblings but the one you asked about is George S. MAXSON born May 30, 1841 Coshocton, Ohio and died May 1, 1906 in Wisconsin.
