Houle name variants

Hello my cousins. Under Houle in the works of Cyprien Tanguay are the following variants:

HOUDE (There is a Genforum for this variant)
HOULE
HOEL
LEHOULD
OULE
DESROCHER, DESROCHERS
DESROCHERE
DESRUISEAUX

In the US, Houle sometimes became HALL (my family in NH), or HOOD if the name was Houde.
In family line I have the following variants, earliest to most recent: Houde, Houde-Desrochers, Houde again, Houle, Houde again, Houle and Hall.
SO THEREFORE: be sure you look under possible variants if you are stuck.

We are all related, and descend from Louise Houde-Desrochers and Madelien Boucher, who were married in Chatea Richer, Quebec in 1654.
