Do you have any idea about the origin of the female name Rosemitha? It's also written Rosemithe, Rosemythe, Rosemita, Rosemite, and sometimes
Rose Mytha,
Rose Mita, or any other one- or two-word combination along those lines. I initially ran into the name in Haiti, and have since found it elsewhere in the Caribbean, as well as among Caribbean immigrants. If it's an invented name, it's not recent--the earliest mention I've found so far is an 1828 birth record from Haiti for a girl named Rosemitte.
