Better Than Some Birth Certificates: Online Y-DNA Databases

Online databases for human Y chromosome STRs are useful for:

  • Genealogists to find family connections
  • Anthropologists to map historical migration patterns and ancient origins
  • Forensic scientists to type and sort male-specific DNA

YSearch contains over 96,000 Y-STR haplotypes, 87% of which tested with FamilyTreeDNA, and allows input of results from other DNA testing companies.

SMGF Y-Chromosome Database contains over 37,000 haplotypes of participants who tested with the Sorenson Molecular Genealogy Foundation.

YHRD (Y-STR haplotype reference database) consists of over 93,000 minimal haplotypes approved by the forensic and scientific community and recommended for court use.

The benefits of Y chromosome testing are detailed in Chris Pomery’s Family History in the Genes:  Trace Your DNA and Grow Your Family Tree. This is one of many works included in The International Society of Genetic Genealogy‘s (ISOGG’s) bibliography of books on genetic genealogy and deep ancestry.

    I strongly recommend you reference also Chris Pomery’s article in the 2009 edition of the Journal of Genetic Genealogy on the ISOGG Website. It is of as great practical utility as his two books – and more up-to-date and has weblinks in it (that do work)

    Peter, I just sent an email to you about U4 mtdna; my oldest known maternal ancestress Hannah Bull, had daughter b. GA 1771.

    See Chris Pomery’s 2009 Journal of Genetic Genealogy article “The Advantages of a Dual DNA/Documentary Approach to Reconstruct the Family Trees of a Surname” at

    Thanks, Peter. Your list will be immediately useful!
