[s]I just came up with a list of names that would be perfect for the sisters. Now I just need to pick two and figure out their last name.[/s]

I came up with a special naming convention just for the sisters.

Triplet 1: Ann Eliza (last name unknown)
Triplet 2: Eliza Beth (last name unknown)
Triplet 3: Beth	Ann (last name unknown)

They are based on the names Annelizabeth & Elizabethann
