Y STR Databases (and/or Searches)
21 December 2009
may find some difficult to work with.
Many companies offer Y DNA testing. Not everyone who shares your DNA line will test with your surname study or company. Y databases attempt to address this problem. Some databases, such as Ysearch and Ybase, are open and allow you to enter your information and become part of the database. Others, such as YHRD, allow you to search using your Y DNA results but do not allow you to add to the database.
Be sure to read the tips before you explore Y
Databases (alphabetical order)
FTDNA - listed below under Ysearch
Genetree [as yet, I have no experience with this]
Genographic Project – not a searchable Y database
OA [as yet, I have no experience with this]
Y Base (Ybase)
YHRD (formerly Y-STR)
Y Search (Ysearch)
DNA Ancestry (Ancestry.com)
You do not have to be a subscriber to add your information to their database and look for matches.
Note to FTDNA customers: Enter FTDNA as the testing company and the results exactly as they were reported by FTDNA; the system will make the necessary adjustments.
I have not yet done this. However, I
am told there is some kind of search option there associated with SMGF, etc.
Y Search (Sponsored by FTDNA)
Open database. Site also accepts GEDCOM files.
Note to FTDNA customers: You can automatically upload your results to Ysearch from your personal pages at FTDNA.
Open database. This is open to all and is sponsored by DNA Heritage, a
You can still search their database but the Sorenson Molecular Genealogy Foundation (SMGF) no longer offers free DNA testing. They announced their partnership with GeneTree in 2007 and stopped offering free tests in 2009. Their samples include DNA from the "old BYU" study. If your Y DNA
This is an anonymous database developed for the forensic community - not
for genealogists - associated with the
The first database was known as the Y-STR Haplotype Reference Database
(Y-STR). In about March 2004, that database was "frozen" and new data
added to the Y Chromosome Haplotype Reference Database (YHRD). The original
Y-STR (ystr.org) database had sections with separate links for Europe,
The sponsoring company merged with FTDNA but there are some search capabilities at the site
Genographic Project (National Geographic)
This is not a searchable Y base but is included here because some
participants think it is. You may wish to submit data to the databases
discussed on this page. If you tested with Genographic it is recommended that
you use the FTDNA free “transfer” option at the Genographic site.
See Tested with Genographic first at:
Note to FTNDA customers: You can submit your information anonymously to National Geographic's Genographic Project via a link on your personal page at FTDNA. The $15.00 fee goes to the project. Important: if you submit to that project, you will be given a (very long) Genographic project code. Don't lose it! Once it is issued to you, FTDNA and National Geographic can not identify you. Also, don't be surprised if some of the results look different. There are two reporting conventions for markers 389-1 and 389-2. One method reports 389-2 as the sum of 389-1 and 389-2 (used by FTDNA) and the other displays the data without the addition (used by Genographic). When information is submitted between these projects, the results are automatically converted. (389-1 and 389-2 are also known as 389i and 389ii.)
< . . . the Oxford Ancestors database does require a members login. However, a "Guest" qualifies as a member. So, just click the Guest button and you are in! In other words, anyone can check this database for mtDNA or Y-DNA. If you check out the Spring issue of Journal of Genetic Genealogy online ( http://www.jogg.info ), you will see a discussion of the size of the OA Y-DNA database. Public information indicates the mtDNA database is about ten times the size of Y-DNA database, if memory serves.>

TIPS FOR USING Y DATABASES
Confusion is normal.
Don't be in a hurry when you do this.
1. Print out your DNA results.
Note to FTDNA customers: You need these tips for all databases except Ysearch (see your personal FTDNA page).
2. Warning - The DYS values on your results page may not be in the same order as those in other databases.
3. Read instructions at each database. Don't skim the instructions. Read them carefully. For example, DYS19 is also known as DYS394. Some databases require numeric adjustments – some automatically adjust them for you.
4. If possible, print the entry page of each Y database site you are using, then copy your numbers on the page, and use that when you make the entries.
5. Some of these databases may list DYS numbers that you do not have - or may not list all the numbers that you do have - that's OK - enter what you have.
6. After entering you information, double-check the screen before submitting. It's easy to make a mistake.
7. Some of these databases will issue
you an user/identification code and/or pass code - be sure to record
Note to FTDNA customers – these codes will not be the same as your FTDNA codes.
8 . If you use the email option in open databases - be sure to keep it
9. If you upgrade, don't forget to add the results to your existing entry.
