John~ Do you have the name of the Cleveland Parish they belonged. The parish name would give me a clue as where to suggest they might be in modern time. Also, if they attended Catholic High School or Catholic College/University in this area? Some of the Catholic High Schools have active alumna associations so if their children attended this might be an avenue. What about military records? Any males who might have served in the two World Wars, Korea or 'Nam? Did the MOORE name literally die out? If not you could try the White Pages on line for a street address or phone number.
