Just send your name, email address, and the details that you already know on yourself, your parents, grandparents, etc. to Ask a Genealogist and, if you're chosen, I'll research your family online for you for free. The results will be published on About Genealogy in a step-by-step article, so if you would prefer to keep your family details private, this isn't for you. No specific details will be published for any individuals that you indicate are still living (no dates of birth, social security numbers, etc.). And remember, the information included in this family history will all be located online and is already publicly available.
I look forward to hearing about you and your family history project!
