My uncle, John J. Ahearn, was born in Somerville, MA in 1909, married my aunt in Queens County, NY, in 1931. John's father was Terrence Ahearn and his wife was Mary Mulhearn of MA. She re-married around 1922 a James St.John of MA. Any Ahearn/St. JOhn connections after 1910 in Boston, Cambridge area?
