Y
STR Databases (and/or Searches)

Bottom line: Recommend you add your results to the two open Y databases and search all databases from time to time. You may find some difficult to work with. Read the tips and be patient. |
Several different companies offer Y DNA testing. It is likely that not everyone who shares your DNA line will test with your surname study or company. Y databases attempt to address this problem. An "open" database allows you to ADD your information - it becomes part of the database. The first two below are open databases that provide entry information options and a pass code. You can search SMGF and "add" to that database by joining their study (free). YHRD allows you to search using your Y DNA results but does not allow you to add to the database.
Be sure to read the tips before you explore the Y
databases.

Ymatch - status not clear to me (the
company merged with FTDNA) but I think there are some search capabilities at
the site

Ancestry.com has an option for others who tested elsewhere to add their information to their database. It is not clear at this time if they intend to use this to provide an "open" database (similar to Ysearch) that will include results from the tests they offer as well as data submitted by others who tested elsewhere or if this is just something for their subscribers. My personal recommendation is to wait a while until more is learned.

Update:
October 24, 2007 – SMGF has announced a partnership with GeneTree
(a commercial company). The implications
of this are not yet clear to me. It was
always known that SMGF was a part of the large Sorenson “universe” but until
now, data submitted to SMGF had no direct association with a commercial company.
The non-profit Sorenson Molecular Genealogy Foundation (SMGF) allows you to search their database. They have DNA samples from the "old BYU" study and are gathering more samples. If your Y DNA results match someone in their database, you can see some pre-1900 pedigree information but will not be given any contact information.
You can include your DNA information in the SMGF database by requesting their free participation kit and sending them your DNA and genealogy. There is no charge and your test results (for most markers) are independently confirmed by a second test (free!). However, you will have to wait several months before lab work and upload of data takes place and since this is an anonymous database, you will need to locate someone in your pre-1900 pedigree information to confirm your personal results. Visit their site for more information. (You may wish to order free kits for all your family members, including females, and participate in their study.)
==============
YHRD (formerly Y-STR)
http://yhrd.org/index.html
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,
===============
Genographic Project (National Geographic)
This is not a searchable Y base (but is included here because some participants think it is). 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.)
===============
OA – I have not tested this yet but according to a December 2, 2006 post on the DNA Newbie list at Yahoo by Phil Goff you can look at data at Oxford Ancestors.
< . . . 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
Be patient.
Confusion is normal.
Don't be in a hurry when you do this.
1. Print out your DNA results. If you are with FTDNA, the results are at the link: Y-DNA DYS Values at your personal page. FTDNA customers do not need these tips to enter their results to Ysearch at FTDNA but do need the tips for other databases.
2. Warning - The order of the DYS values may not be the same as the one you are familiar with. Therefore, extra care is required when making entries.
3. Read instructions at each database. Don't skim the instructions. Read them carefully. For example, DYS19 is also known as DYS394 and it appears both ways among the various databases. Some databases may require numeric adjustments – some may automatically adjust them for you.
4. You may wish to 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 those (they will not be your FTDNA codes).
8 . If you use the email option in open databases - be sure to keep it current. If you upgrade, don't forget to add the results to your existing entry.
