I just discovered that 120 East 122nd Street in Harlem is still there.  It was the home of my great-great grandfather, Thomas Trainor, who came over from Ireland at 15 in 1820, had a carriage business at 200 West Broadway in Greenwich Village, and is buried with the wife he outlived and perhaps seven other family members, including two kids he outlived as well, in just two graves in one plot in Calvary Cemetery, the country's largest. (It's that giant field of headstones you pass through where the Long Island Expressway crosses the Brooklyn Queens Expressway.)
