There is also a VERY new DNA test that that females can take to reveal cousins, grandparents and relatives up to 4-5 generations back. 23andMe and FTDNA www.familytreedna.com both offer them.
However, the data bases of people who have taken the test are still relatively small and you may not find a match. And they are still a little bit expensive.
I’ve already did the mtdna test but I’m more interested in my husbands ancestors (he will be 82 in Feb) & my dad’s side (only 3 males left in the family). I find it interesting that the closest ancestors for both have different surames but then its probably 250/350 years ago.
