Nice to hear from you. Sorry for the delay, busy, busy etc.
The only MUISE I have is my maternal grandmother who, I believe, came from Nova Scotia, as that is where my mother was born. She married into the SWEENEY family, which I have traced back to 1786 or thereabouts.I see there are quite a few Muise names in the LDS lists, mostly from the same area but no Ellen. There is an Elaine however. I would be interested to see what you have.
