I have always thought that our first DYS listed, the 393, being a 12, was an impediment to being a Robinson, being so many started with 13. I see from the FTDNA Robinson study listed below that there were 17 that started with 12, and many more, of course, that started with 13 in our R1b group.

Here's information from the Bennett name study and their DYS393=12.
When viewing the chart, note that DYS numbers in red are the faster mutating markers. Mutations (from the modal) are highlighted with a blue background. SNP testing has confirmed our Haplogroup to be R1b1a2a. Note also that each person in our group has an allele of 12 at DYS#393, an unusual occurrence, happening only about 2% of the time. We are participating in The Border Reivers “DYS393=12” Y-DNA Study to learn more about the possible deep ancestry ramifications of this splinter group. This haplotype, called ht-35, may have originated from individuals who took refuge from the last ice age (about 10,000 years ago) in Anatolia. To view all the Bennett Group results, visit the Bennett Group chart at FTDNA.com (See link in sidebar). Our Ipswich Bennetts are listed as Sub-group 8a in the FTDNA chart, and are easily recognized by DYS#393=12.
