To everyone and anyone whose yDNA haplogroup is J-M267 and believes themselves to stem from a Rapoport lineage, there is an FTDNA project picking up steam that involves you. Please join the group for further details: https://www.familytreedna.com/groups/cherson-family-project/about (and don't let the name of the project deflect you: this is about the Venetian Rapoports).
