That is interesting. I have a George Walker from Mo,. who married a Ida Mae Ringheim, Ringham in Watonwan county and maybe Martin county. I am not sure yet if that was her who was at Waverly Martin county, mn. George walker who may have had family in Ohio. Or it is the family that lived in Illinois.
Ringheim In 1880 census at mode blue earth county along with Hollison.I suspect Hallesen in norway. I wouldn't mind learning more about your Walker family.
