I looked through my Family Tree Maker program and found Arnold Wenning, but could not find Isadore Wenning or Martin Wenning.
My info indicates Arnold was born 30 Dec. 1917 in Dayton, OH and died 24 July 1971 in Celina, OH.Arnold was married to Rita Louise Hohl.They had five children: Joseph, Margaret, Linda, Charles, and Thomas (birth dates available if you would like them).
Arnold was the son of Frank Matias Wenning and Mary Carrie Kaiser.Frank and Mary had 7 children.I have additional details on these children, their spouses, etc. if that helps.
By the way, I'm also related to Alton Barga/Norma (Meyer) Barga (formerly of Russia, OH).
