I recently participated in Sorenson's free DNA database. They send you a free DNA kit which you return with a copy of your pedigree. You remain anonymous in the database, only your grandparents and beyond show. You have to be a male with the Eller surname to participate. If you are a female descendant, you will need to ask a brother, uncle, etc. If you are interested, please go to http://www.smgf.org/and click on Participation Kit. I found out I was not who I thought I was.
