Professional Genealogist, Genetic Genealogist, Musician, Chef, Entrepreneur. Member of the Sigma Chi Fraternity. I've became interested in genealogy since I was just 9 but began seriously researching my family roots in 2009, finding a special expertise with the Portuguese Jewish community of Amsterdam, Southern New Jersey Jewish Agricultural Societies, and locating living relatives. Besides being a volunteer Curator on Geni, I am also a volunteer Search Angel. I am currently working as the Lead Forensic Genealogist for DNA Labs International. I DO NOT work on any Forensic cases through Geni (this would violate the NDA I signed as a Curator), so do not expect to find any information about the family trees relevant to these cases available through my Geni account.

What are those numbers next to my name and other profiles I manage?
This is a Genealogical numbering system for the Nunes Vaz family of Amsterdam which is a modified version of the Henry system.
