Hi, if you are the direct male line descendant of a member of the Portuguese Sephardi communities of Amsterdam/London and their associated communities in France, Germany, Italy, and the New World, please contact me. Myself and Wim Penninx have just begun a DNA project that will be focused on these communities in collaboration with a larger archival research project. For now, we are focusing on the yDNA but we hope that in the future we will be also able to expand to mtDNA and of course, utilizing Autosomal DNA.
