My mom has been looking for your messages...she was having problems getting into her box so that could be why your messages have bounced.
Eunice Braan is the only listing in the San Mateo phone books and we don't think that she keeps in contact with your sister. You can send your messages to me and i can forward them to my mother. She is currently staying at my house so we have been sharing the messages i have been getting. We will let you know of any information that we come across where the Braan family is concered as we find it.
