Why the Database Size is Essential

Whether your goal is to verify your genealogy or to discover your deep ancestral origins, the size of the testing company's database is of fundamental importance. To get the best and most accurate answer, you want to compare your results with as many others as possible, which means choosing the company with the largest and most robust database. Family Tree DNA is in the lead—Our databases are several times larger than all the others' combined!

Customers and their testimonials

While at a trade-show in the UK, a few people who tested with another company came to our booth and asked: "I got their results and now what?" Unfortunately for the customer, they were lured by a low price but could not do much with their results, so they ordered a new test from us. Also, in a couple of cases, the other companies gave them wrong Haplogroup assignments. Family Tree DNA receives orders on a weekly basis from individuals who previously tested with other companies, but choose to retest with Family Tree DNA. Here are just two examples of letters from individuals that tested previously with another company. They speak for themselves:

"We had my brother's Y-DNA tested by another company. (Mistake!!) We know wish to have a Y-DNA67 test by FTDNA and to join the Group Armstrong Project. The co-administrator of the project, sent me the link to the group's promotional offer. I have filled it in and am sending it to you. Please send the kit directly to my brother's address on the form and bill my VISA seeing it's my gift to him."

"I did three DNA tests with another company and I am getting no reply. Do you have connection with them where the DNA testing information can go to you so I can get more information? I am lost. I sent in what I needed but got nothing to show where we come from or anything. Please help me..."
