I spent quite a bit of time doing some comparisons, etc of data. and you will like what I found. I will not use complete names as this is a public website. However, I compiled the information and saved it on a pdf. I will send it to you as an attachment as I do not think we can send attachments on this forum. I will be sending it to Jim, Chris, Leonard, Ann and Mike. If anyone else would like a copy I can send it as an attachment in an email directed to you. I also have the complete cvs Excel file which I am not sending.
Jim-thanks for placing your surnames on your page. That helped me see you on Rita's matches.
I had access to Mic, Rita and Mike's matches and the others were matches to each of the three of us.
Following is the gest of it. In the pdf I give snp start and end locations and cMs.
Of people matching Mic:
Rita- 1st Cousin
Of people matching Mike:
Boyce-5th Cousin Remote
Jim-5th Cousin Remote
Of people matching Rita:
Strangely (or otherwise- as in the randomness of what we inherit) Rita matches Jim and Mike but not Mic, even in the CVS comparison where it measures as low a 1cM).
Chris, as administrator, will have to tell us if Boyce, Heidi and David are in the McCown project. They would be in the Family Finder results page of the administrator's page and not on any public page. Chris would ba able to see this but not the rest of us.
Heidi and David descend from Mary McCown (daughter of Alexander) who married William Nutt
On 23 and Me I also match a 3rd cousin of Heidi who is of this line but does not seem to be on FTDNA.
Boyce descends from James McCown (ca 1775-1820) married Sallie and through their daughter Sarah Ann McCown b 1809 Camden Co, SC d 1889 Camden Co, SC) married Jesse Salmond Nettles.
So, from what I am seeing this line is somehow related.
Since Jim, Boyce, Heidi and David are not in any of the projects I administer I was unable to see their matches.
However, to make a longer story shorter, all of the above people do match one another when placed on the chromosome browser and when printed out in Excel from the CVS format which bases the matches on 1cM rather than the 5cM normally used by the Chromosome Browser.
The matches we have are all very small which is why Boyce and Mike do not match me, Rita and my matches. I do not know if Boyce and Jim match at all even though they both match Mike.
Rita (Mic's 1st cousin) and Jim match as 2-4 cousins with 73.04 cM
But Mic and Jim did not at all.
The matching is occurring collectively on Chromosomes: 2,3,4,7, 8, 9, 10, 11, 12, 15
Not everyone is matching everyone on each of those chromosomes.
