John Dobbins

My husband and I are doing his family history and we're not having very good luck. We're looking for any information on a man named John Dobbins. All we know is that he was married to a woman named Vivian and they had a son, John Dobbins Jr. I have looked at familysearch.org and can't seem to find a single clue. Any help anyone can offer would be greatly appreciated. :)
