JOHN MCCARTHY (b.1813 ?) married Elizabeth O'Hanlon, lived in NYC, and as a STONE MASON worked on the WALL AROUND CENTRAL PARK in New York City. Arrived in US in 1850s. Daughter ELIZABETH A MCCARTHY (b.1843), worked for B.Altman in NYC, married Oscar B Marcato in 1877. Does anyone have ANY possible connection to this MCCARTHY family ? I've reached a dead end here. Thanks for any help or recommendations.
