This wiki traces the Y-DNA and mtDNA of Mayflower passengers, their spouses, and the spouses of their children and grandchildren. It does ''NOT'' work with autosomal DNA tests (such as AncestryDNA, 23andMe, etc.). Because we inherit autosomal DNA from ''both'' of our parents (who in turn inherited their DNA from both of their parents, etc.) the amount of autosomal DNA we inherit from each of our ancestors decreases every generation. After about 5-6 generations we no longer inherit ''any'' autosomal DNA from some of our ancestors. Almost all living Mayflower descendants are at least 10 generations removed from our Mayflower ancestor. That far back, we only inherit DNA from a tiny fraction (''much'' less than 1%) of our ancestors from that generation. Even if we are lucky enough to have inherited autosomal DNA from a Mayflower ancestor, there really is no way to document which ancestors from that generation we inherited any of our DNA from.

This wiki traces the Y-DNA and mtDNA of Mayflower passengers, their spouses, and the spouses of their children and grandchildren. It does NOT work with autosomal DNA tests (such as AncestryDNA, 23andMe, etc.). Because we inherit autosomal DNA from both of our parents (who in turn inherited their DNA from both of their parents, etc.) the amount of autosomal DNA we inherit from each of our ancestors decreases every generation.

The vast majority of descendants of Mayflower Passengers will NOT have inherited their Y-DNA or mtDNA from a family in this project.

Methodology

The focus of this project is on using advanced Y-DNA and mtDNA tests to document the patrilineal (all male line) and matrilineal (all female line) lineages from the Mayflower. For each surviving lineage from the Mayflower, this will provide the most comprehensive Y-DNA and mtDNA profile that is possible with current commercial genetic testing technology. When available, we will make use of prior genetic genealogy research related to these lineages (e.g. Y-STR test results) to provide supporting evidence and to guide project recruitment.

Through this approach, we aim to achieve the following objectives:

  • Place the Mayflower passengers and crew into the broader human Y chromosome tree by determining high-resolution haplogroups for individual paternal lineages
    • this can help provide a demographic-level picture of the ancestral origins of the groups comprising the 1620 Mayflower voyage
    • these efforts will also likely aid in more general research of the human Y tree
  • Identify unique, stable genetic markers for individual paternal lineages
    • in some cases, it may be possible to identify one or two markers that confirm patrilineal descent from a single individual from the Mayflower
  • Use the results to aid in genealogical research associated with the Mayflower passengers and crew, including tracing ancestry further back within England, Holland, etc.
    • testing related lineages that stayed in Europe can be particularly helpful here
