Dutch Sephardic Jews with R1b1b2 haplogroup - DNA Forums - Bennett Greenspan (of FTDNA) said that there was a small population of Dutch Sephardi from the R1b1b2 haplogroup.
I had wondered if Henwood could be one of these people, but I need to have a much deeper test done to find out. Hen is a surname with Sephardic Jews in Spain. Wood was a surname found in Holland. In the Spanish tradition, surnames are combined when marriage takes place for the female. Thus, Henwood could be created from two families.
