I don't think I can help with their parents, but they appear to have had many more children.In the 1900 census the children listed are:Alfreda, 9, Oliva, 6, Amede, 5, Eugine, 2, and Winfred, 0/12.Both parents say they immigrated in 1880.
In 1910 the children listed are:Alfreda, 18, Olive, 15, Amedie, 14, Eugene, 12, Wilfred, 10, Emile, 6, Hormeidas, 4, Irene, 3, and Blanch, 1.Leon immigrated in 1882 and his wife in 1880.
In 1920 the children still at home were:Amede, 24, Eugene, 22, Wilfred, 19, Emile, 16, Hormidas, 14, Irene, 13, Blanch, 10, Bertha, 8, and Andrienne, 7.
There's a marriage record for a Leon BELANGER to a "Rosede Leina LOCOURTE on 24-Oct-1887 in Westbrook, Cumberland Co, ME.I can only see a transcription, not the actual record.
There are ME birth records for some of the children that spell their mother's name as LECOMPTE, LECONTE, LECOMITE, or LECOUTE.
