Mass 1920's Gervais family

Hi, I am searching for any members of Alexandre & Jeannie (Quinn) family from the Lowell/Chemsford area. They had 6 children ~ Mary,Joseph,Mary Ann,Frank,and Alex Jr. All were born in Mass in the early 1900's. I have the census with Frank's family living with his parents -1920's. I believe Frank is my grandfather who I know nothing about. Thank you So much. Sharen ~~ Also I believe Mary Ann moved to NH in the 40's.
