I am searching for information about the family of my great grandfather, Maurice Albert LeFranc, who was born in Calais around 1883. He was the only one of his siblings to immigrate to the United States. The rest stayed in France to the best of my knowledge. He had at least six siblings names Adolphine, Noel Auguste, Lucie, Julienne, Adolphe, and Jeanne Georgette. Their parents names were Noel Francois LeFranc and Louise Peant. I know there are other family members with the names Allain, Duquesne, Poisson, and Duquenoy but an not sure how they are related.
