I did Ancestry DNA with my immediate family...and here are the results. It is an interesting process. My DNA results are mostly what I expected. I have exploring the website, and found that very little information is in their database. My sister has had the genealogy hobby for about the last 50 years, and she has a wealth of information about my family.
The site is only as good as the database, and it depends on individuals adding information. I was surprised that it had about 4000 2nd, 3rd, and 4th cousins for me.
They do have information from public records available...for a price.
This is Hubby's DNA. This is as expected.
