My Grandmother lived in Washington, DC. She also mentioned that we were related to the John Carroll. The only Carroll that I've found goes like this: Martin O'Leary(my gfather)>Richard O'Leary>Dennis O'Leary + wife Ann Carroll (daughter of Owen Carroll and Alice Murphy)Richard married Mary Ann Cleary > Martin Cleary + Bridget Geary >Michael Cleary + Ann White. Both the White's and Carroll's at some point were in New York...that's where Ann landed.
If these names sound familiar email me!
