Request Genealogical Information from Family Members
Dear (Your Relative's Name),
(Insert paragraph of family news here.)
You may know that I am gathering information about our family history. I am currently working on the (surname) branch of the family, and I wonder if you could give me any information about them. In particular, I am looking for (short list of information that you need, such as names or birth dates of specific people).
I appreciate you taking the time to help me out. If you would like, I would be happy to send you the family information that I have already collected for this branch.
Say hello to (name) for me!
