I am trying to find my step sister. She lived in Tampa, Flordia the last knowledge of her. My step dad,who has raised me has been trying to find her for a long time now, but has not be able to because he doesn't know her married name. I am trying to get more involved especially now because he was diagnosed with Lung Cancer this week that has gone into the lymph nodes and only given three months to live. How to I go about finding someone who I only know her maiden name?
