There are no marriages, through 1998, for any Johnetta BOHN in Cuyahoga County. The closest was a Joan BOHN to Thomas KRAMER, date unknown.
You could contact the Cleveland Auditor's office and ask who was the owner of the property at 2611 Garden, in 1956 and later. From that info you could look for them (or their obits) or perhaps, a subsequent owner may have been Johnetta.
