Hi, Allene, Answers are in your paragraph, below. On May 30, 2011, at 9:03 PM, Allene Goforth wrote: > Working across at M[a]cAdam (only one of the five uses "McAdam"): What > is the 5/5/ for?

I was guessing it > was in the 1600s or a bit earlier. What is the 15.15 and 28 at the end? Above the diagonal are the RCC values for the TMRCAs of the common ancestor of the surnames of the intercluster. That is, 15.5 is the RCC of the MRCA of the McCords and the McAdams. That corresponds roughly to 1130 AD (the intersection below the diagonal. 28 is the RCC of the MRCA of the McGonigles and the McAdams, and is roughly 470 AD. Hope this helps you (and others) to interpret how to read the junctions on the tree. - Bye from Bill Howard > > Thanks, > Allene > > R1b1c7 Research and Links: > > http://clanmaclochlainn.com/R1b1c7/ > ------------------------------- > To unsubscribe from the list, please send an email to DNA-R1B1C7-request@rootsweb.com with the word 'unsubscribe' without the quotes in the subject and the body of the message

Bill, One more question. May I ask where you plan to publish this data (if you are allowed to tell me)? Thanks, Allene
