I'm getting confused because I don't know some of the shortened versions of first names. I'm finding Sally or Sallie for Sarah. I can't figure if my gggrandfather had 1 wife or two. Also what are some of the proper versions for the following names.
Betsy or Betsie or Bitsie
Peg or Peggy
Sally or Sallie
If someone is knowledgeable on some of the common ones for both male and female names, can you please post them??

Thank you
