DNA
Sometimes you can run into a brick wall in your tree and you just don't have enough evidence to make that next step back in time. A DNA test can sometimes help to make a link to a particular family name if you find you share common DNA with people who have the same or similar surnames as each other. If you are lucky then you may get a match within a few generations and discover some Costello ancestors. Additionally, the modern DNA test can give you a breakdown of your ethnic mix - you may be surprised at the results!

Birth, Death and Marriage Records for the Costello Genealogy
