Thanks for your reply. I have not found them in the Ohio death index; after your note I checked by first name every August (e) in the 3 year period in the index, to no avail. It is possible that they died out of state (IN or MI?, where they may have had relatives), though they are listed in the 1920 census in Hicksville, and were apparently still there in early 1922 when my great-grandmother died while visiting them. I'll continue my search, hoping that Mary's info will help me find data on her parents, my greatgreat-grandparents.
