Found a MA marriage index for Edward Langlois in 1948 in New Bedford, MA vol. 84 pg. 192
Cannot yet find a marriage index for who he married in 1948 but am assuming it was Lodia L'Heureux since he died in 1960 & she died in 1996 as the widow of Edouard H. Langlois
SS Application & Claims index for Lodia Marie L'Heureux shows name changed to Lodia Marie Langlois on 3 May 1988
