Looking for Robert Mccaughey Jr of Ohio

I am presently researching and looking for information about my husband's great great grandfather, Robert McCaughey who married Mary Gregg ( I do believe she was married to a Robert Gregg, previously). I have limited information about this Robert although have information about his father and also his offspring. Would like to know if there is anyone connected to this family who might have information about where and when he died and where he might have lived and was buried. Marlene
