How nice to hear from you.You are most welcomed to contact me off list at:email@example.com
Briefly, as a male you can test your Y-chromosome DNA and help the group find out which Derby lines connect to yours.The Y-chromosome is passed from father to son virtually unchanged since mankind began.The minor changes in the DNA helps put families together.
DNA testing is the most accurate tool a genealogist has and can help prove or disprove your paper trail.It can tell you if you have a common ancestor with others with your surname and it can often help break down brick walls.
DNA testing does NOT replace traditional genealogical reseracher, but aids it.We all know that our paper sources are incomplete due to ancestors not documenting everything, due to lost or destroyed records, and due to errors in the records.DNA testing is more accurate but till not tell you the name of the common ancestor when you do find a match, nor when they lived nor where.It is up to good research to do that, but it does help you find people to whom you are definately related and tells you which lines you do not have to research.
I spent hundreds of dollars on a person who surely appeared to be related on my Ogan line.The guy had my ancestors' names:Peter and Euphemia (not common) in his grandchildren.He lived in the same areas, etc., etc.We tested his descendant and mine and they aren't closely related at all...maybe in the cave days.Wish I had heard of DNA testing before I spent so much money!
ALSO, DNA testing for genealogy has nothing to do with the part of your DNA that has health issues.Insurance companies, doctors, etc. will not be contacted.Testing will not get you on or off the FBI's Most Wanted List, also.That is a different part of the DNA and in testing you become a number with the lab so they have no idea who you are.
Do write me off list and ask any questions you wish.I don't want to take us more space.
