Dont know if we are talking about the same brothers but... Robert M. Sullivan and John L. Sullivan both born in the 1920's are part of my family line. They both lived in California, off and on, in the 1950's-1980's
If you are still looking and they fit in your family, do you know of any other family or birthplace or middle names etc. I have a very large family of Sullivan's and information on this generation. e-mail me at
ceceliabenson@pdq.net if we have a fit.
