Hi Michael, I'm researching my ggrandfather, Alfred Delaney Hingerty (1800-1875) b. Washington, DC. he was a boatswain on the Constellation from 1840-186? He outlived his first 2 wives. He and first wife Mary had 5 children. He and second wife Ellen had 5 more children. He and 3rd wife Elizabeth had no children. I am descended from George W, youngest child with Ellen. I am trying to find his parents, father possibly named John, mother unknown and both possibly from Tipperary. Any info you have and wish to share would be greatly appreciated.
