It appears he may be the son of Onezime/Ousime/Oleime LaFlamme and Zoe Lessard, from the records of their other children. Marriage records did not give the parents names. Didn't find a 1920 census for Biddeford to confirm any relationship. In 1930 he is living with sister Emilia LaFlamme Desrochets.
