Sorry, Pat. I think I made an error in my previous message, because there were three individuals with the given name "Etienne," not only two. Goes like this:
Pierre GOVEREAU - 1620sFrance Pierre GOVEREAU - 1650sFrance Etienne GOVEREAU Etienne Adrian GOVREAU - Canada, PQ Etienne GOVREAU ......... Joseph GOVREAU - 1830sUS, Vermont
Notice that the spelling changed with the "second Etienne." After Joseph, in Vermont, it changed again, to GOVRO and GOVERO. Those who entered the US from Ontario (rather than Quebec Province) tended to use the original French spelling GAUVEREAU.
