antonette katinka maria mortensen

Yesterday I saw a post dating 2001 on google,'newsarch.rootsweb' I contacted Rootsweb site but they are not related. The message is incomplete but it has been posted by someone looking for anyone that could be connected to her grandmother Antoinette Katinka Maria Mortensen. I believe her grandmother was my grandfather's sister...Mathias Kristofer Mortensen, left Bergen the same year, different month 1892 from Bergen..leaving behind their sisters Ragna Louise, Karen Marie, and their parents, Mathias Chirstophersen Mortensen, mother Alberthine Gothilde Knoph- Mortensen...I have a fair amount of information and would love to share it with this grand daughter. Thank you.
