Ancestor Mysteries #4

#4: The 2nd Mrs. Levin Hubbard: Levin Hubbard's 2nd wife is a complete mystery as to vital statistics. Name, birth, marriage, death and locations of all. Estimates of BMD can be made and strong guesses as to place of marriage and death. Some concrete information would be nice. Details abound on Levin's 1st and 3rd wives, but not the mother of my Sarah Hubbard. [Not even in Salt Lake!]
