Hello again Ed, please take a look at the FTDNA R-YP276 Norse-Gaels site. Your R-YP278 would descend directly below the haplogroup R-YP276, and directly above R-YP275. We have not yet created the R-YP278 haplogroup category in our site template. Would be pleased to create one for your haplogroup if you wish to join the project. Please review our site overview, background and goals. If you have any questions, please feel free to email me. Thanks again and best regards, Gary H.
