Hi Lisa, just wanted to let you know that throughout my researching my LeGallee and LeVallee families, I have come across most if not all of the names you have mentioned. My GGGrandmother was Rachel LeVallee b Alderney abt 1806, she emigrated to Quebec, Canada and married Thomas LeGallee. I don't have alot of info about him but when he passed away she remarried a Jean Lenfestey. All of the surnames I have mentioned are Island names, seemed they liked to marry amongst themselves. FYI, Abraham Lenfest(e)y married Thomasse Brehaut in 1668, Guernsey.
You can find lots of info about the families that emigrated to Canada in the Drouin Collection.
good luck!!
