Burl Green's first wife was Mary Emaline Lee. I found it on one of the children's death certs, Uncle Pink's I think.

I'm partly responsible for the Brantley/Brown myth for Green's first wife. It's a long story (I'll tell you if you really want to know), but Green is married with children in 1860, while both Mary Brantley and Mary Brown, the two previous suspects, are still single and living with their widowed mothers in 1860.
