Good question. Well I had to place my people in a given month / year, so to do this, I mapped out a January 1, 1907 chart of two families: the Poulin and Vachon dit Pomerleau families. Their relationship is doubly complicated by the fact that two Poulin brothers married two Vachon sisters.
Nazaire Poulin and Victoria Vachon were one family group, and Raoul Poulin and Lucia Vachon were the other.
In these two graphics, deceased members are in a muted gray.
