Well I kinda have to change Melodys date for obvious reason, and I might even move Sophianas Wedding date (to a later age) and then they would all change.
Laurence has a daughter named December who was born in '09. And although they're not very important, Siggi has a daughter named Doll in '08 and her sister has a daughter named Holly in 2010. Rosalinda has Tabbetha in '09 as well. :) I think I have a list of exact dates on my profile somewhere...
