The Rothwell, Rathwell and Radwell surnames appear historically associated with Ireland and Great Britain. The Rothwell, Rathwell, Radwell Surname Project objectives are to: 1) Identify and categorize various, distinct Rothwell/Rathwell genetic lines. 2) Help project participants determine to which distinct line they belong. 3) Determine to what extent various Irish and Great Britain lines are genetically related. 4) Determine where the specific Ireland and Great Britain Rothwell/Rathwell lines originated. To join the Rothwell, Rathwell, Radwell Surname group WITHOUT an existing Family Tree DNA test, please read the following recommendations: 1) Males with the Rothwell/Rathwell surname--please sign up for the YDNA-37 or YDNA-67 test if possible, since it will give a fairly definitive proof of relationship. 2) Females who have Rothwell/Rathwell surnames in their ancestral pedigree have two choices. If possible have a male Rothwell/Rathwell in your close family line take the YDNA test as mentioned above. Or you may wish to participate through the FamilyTreeDNA Automsonal DNA test referred to as the Family Finder test. While results will not be as definitive as the Y DNA, the Cousins Matching List may be helpful in determining whether you are related to the various Rothwell Rathwell and other surnames that are closely related and associated Families. 3) Males with a non Rothwell or Rathwell surname yet believe that there is a possibility that their ancestors Surname may have been at one time in the past or has a modern day change in spelling can take the Y DNA test to see if they link into the Rothwell Rathwell Y DNA Haplogroup membership tree. Again it is recommend to at least start with the Y DNA 37 and if possible Y DNA 67 test . However please note that at anytime it is very easy to sign in and request and upgrade your test to a higher level at a later date. Email me if you have any questions.
