Here is the birth certificate, and the reason I know it is hers is because not only does the birth date match the information I already had, but so do the parents names and parents birthplaces.

I highly recommend that if you have not tried searching over at familysearch.org that you start now! I never thought the site would have anything useful on my lines but boy was I wrong. I am definitely glad I started looking there.
