This Project is created to assist members to find possible relationships/relatives, via ancestors who have lived in, or passed through, London and/or Middlesex in England, with the reference to London, including the Greater London area, or, the whole of the London metropolitan area. Members are recommended to undergo the Family Finder Test, and, for males, to also undergo the 37 marker Y-DNA test , in addition to the Family Finder Test, and, if wanted, a higher level (greater number of markers) Y-DNA test (although, the Project Administrator regards the 37 marker level of Y-DNA testing, to be sufficient for Y-DNA testing), and, for females, to at least undergo the Family Finder Test, and, if wanted, an mtDNA test. Beyond the tests recommended above, which are recommendations, and not requirements, and, the expectation that a person's ancestry involves at least one ancestor who lived in, or, passed through, London and/or Middlesex, no requirements are imposed for joining this project.
