Researching Family Tree

Hi! Allards I am trying to research my family tree. I need help on any information on a Maxime Allard from Canada and his son Le'andre Allard who was born in 1853 in Canada and he married a Marie Louise Dumont. They had My grandfather Omer Allard in 1895 in Providence, R.I. He married an Angelina Tancrede, Who also went by Aldea. Omer had lived in Blackstone,Ma. They had seven children. One of them is my mother who doesn't have much knowledge of her mother and father since her mother died when she was 7 years old. Her father than gave her twin brother and her up. I believe they were put in forster care and was in an out of different homes some in which were family members. Any Informationthat you are able to give to help me with my family tree will be appreciated very much.
Thank you all!
