I descend from the Tipton County Morrissett's on my paternal grandmother's side. In some of my research years ago, I found the name spelled many different ways--Morrissett, Moriset, Morisset, Morisett, Morissey, Morrissette, etc. Could Marcy be yet another? Never ran across it that I was aware of, but as I was reading your post, the thought just struck me, especially since the pronunciation of Morissey is probably not very far from Marcy. Wayne
