It looks like you have a recLOH in your line, and that the differences stem from a single unusual mutation event which resulted in the addition of 2 extra copies of the old DYS464a allele. The genetic distance in this case would be one, so the two lines really are close. It certainly would help to compare the most complete haplotypes possible.

View at http://www.worldfamilies.net/surnames/c/camp Tester A is my line with origins in VA 1740 to 1760 Tester B is from the Bahamas in 1875 as the earliest date. Haplo is l1 I'm uncertain how to interpret these results. Any help is appreciated. Is this one that getting the second person to upgrade would help? That's my choice, but it may not be an option, Lolene ------------------------------- To unsubscribe from the list, please send an email to Y-DNA-PROJECTS-request@rootsweb.com with the word 'unsubscribe' without the quotes in the subject and the body of the message
