The French tradition of identifying someone as Amerindian was the following: If a father married an Amerindian then the children were french, if one of his sons married another amerindian then his children became amerindian. Therefore you could have cousins who would be amerindian and others french. If a woman married an amerindian then she would become an amerindian. This was at the beginning of the colony. This practise also changed with time depending on if you lived on the reservation or if you were ostracised from the reservation. The laws are very different today I hope this information helps.
