Susan E. Cramer's husbands George and Levi

I understand Susan E. Cramer married one of these Sweetwood brothers, and some time after his death married the other. What I would like to know is the date of death of the first one she married and/or the marriage date of the second marriage. I would also like to know the exact date of birth of Susan's daughter, Leah A. Sweetwood.

Leah married George W. Smith. Depending on the timing, Leah could be the daughter of George or Levi, and I want to make sure I list the correct one. My girlfriend descends from Leah.
