Jim Berry is the administrator, and I am the co-administrator of the BERRY project. There are over 110 participants, at least 40 distinct BERRY lineages including multiple haplogroups. On the 1790 US Census, there were approximately 350 Heads of Household named BERRY. Virginia, Tennessee and Kentucky are not included in the 1790 census -- all three being hotspots for BERRY-ness, so a conservative estimate would add 50 households. I can't even begin to estimate the number of BERRYs in other countries. I am the administrator of the DILLON project and Richard Dillon is the co-administrator. We only have 15 participants. There were only 21 DILLON Heads of Household on the 1790 US Census, but I believe that number escalates dramatically after 1850 when the Irish potato famine immigration was at its peak. DILLON also has a fair number of variant spellings which I haven't tried to find on the 1790 census. I am an 'unofficial' administrator of the ALEXANDER project. Roger Alexander is the administrator. The 1790 census numbers for the ALEXANDER surname are remarkably similar to the BERRY numbers and the number of participants and separate lineages are also similar to the BERRY numbers. Most of the early participants of both the BERRY and ALEXANDER projects -- including the administrators -- fully expected most BERRYs or ALEXANDERs in America during the Colonial era to be closely related. I'll just repeat the same thing that I said earlier. The most powerful lesson I take away from Y-DNA testing is that finding the same surname in the same geographical place in the same time frame does NOT necessarily mean that they were closely related -- genetically. We are seeing this over and over on both the BERRY and ALEXANDER projects. It is not as apparent in the DILLON project, but 11 different lineages out of 15 participants is quite a spread. However, this project was dormant until last Christmas when Richard and I stepped in. I was an art major in college. I have been retired for 13 years after working in the non-profit art world. I have no science background at all, so the fact that I have even a tenuous 'grasp' of Y-DNA is an amazing turn of events. My brother -- surname GLASS -- is one of the members of David's R1b- U106/S21+ project, but I am his contact person since he cares nothing about either genealogy or DNA. As a person heavily involved with basic surname projects, I am eternally grateful to those who have started specific Haplogroup projects because I don't have the knowledge to talk about Haplogroups in depth and certainly can't do the math which seems such an integral part of the analysis. Most of the participants in my projects are truly not interested in Haplogroups anyway, but for those few who are, it's a pleasure to be able to send them to someone who can help. Carol Vass Kent, WA
