Have been stumped on this one for years, need help. John Henry Latta b. 1825 PA went to LaGrange Co. and marriedMary E. Cunninghamb. 1841 Ohio.After having 4 children between 1859 and 1867 they moved to Missouri, where William died. Later Mary E. went to Kansas where she died in 1907. I have never been able to identify the parents of Mary E. Cunningham. I have Lattas coming out of my ears, and have them pretty well nailed down, but the Cunningham part is driving me nuts. Any help or suggestions appreciated.
