Thank you for your kind response. The John F. Heslin and Winnifred L. Chisholm, whom I believe are my great grandparents, resided on Gershom Ave. in Lowell, MA. They had eight children; Muriel my grandmother, Alice, Duncan, John R., Kenneth, Winnifred, James P. and Robert P.
The fact that your father John F. Heslin was born in Lowell in 1895 is quite a coincidence since my great grandfather John F. Heslin was probably born about that time, as he married Winnifred Chisholm whom was born in 1893 in Lowell and their first child Muriel was born in 1914.
I would be very pleased if you shared more information on the Heslin family that might facilitate my research.
