I would like to amplify Shirley's comments, as the number of Branch H-groups grew by one when I took the DNA test. My family comes from England, but is not related to Peter or Christopher. My group is J2. I guess that many of us have been looking at the Branch family history as related by various authors, and seeing mentions of Lord Mayors, Knights, martyrs, merchants and others of high rank and none. There is a whole lot of guesswork going on there. It is like an archipeligo of islands, each with a group of related people, but where no-one knows how the others got onto their islands. I am related to a verifiable population of Caribbean people going back to the mid 1600s. My ancestors went to the West Indies within a few years of when Christopher and Peter wnnt to America, but we are not related. Later, many with 2 to 300 years of living in the Caribbean went to the US, I must be related to them-so where are you? My main interest is in finding to which of the various bands of Branchs in the England of the middle ages I belong. can any one help???
Hull , of course, is an English city in Yorks, so could just be a geographical name ( George of Hull)
