I need some help. I can’t find My Great Grandmother (Phoebe Ann Medara/Madera) anywhere other than listed below. I would like to be able to validate her maiden name and where exactly she was born so I can get an understanding of her side of the family. Also I would like to find a marriage date and possibly a death date.

Children:
Jemima, abt 1869, PA
