Easy family research

This is the effortless way to do family research. You provide a little family history, and we take it from there, merging and matching the data for you.

Find your missing ancestors has been a tremendous help to me in my family research...I have discovered several dates that had eluded me, as well as finding some unknown ancestors that I didn't know existed. I also found 2nd & 3rd cousins that I never knew prior to my experience with OneGreatFamily.
