There is an SSDI record for WILLIS OWES who was born 1921 and died in Cleveland, OH in 1977. The info matches with a WWII Army record, both on Ancestry.com. A public record search for RUTH did not turn up anything for her, but there is a NICHOLAS T OWES born 1945 in Cleveland, OH. He might be their son. Try 216-555-1212 for his number. Perhaps if he is their son, he might be able to tell you something about HELEN. Good luck!
