Genealogy dna testingDNA testing for ancestry. Genealogical dna testing. Genetic genealogy.
Probably the majority simply don't know what to think about genealogy dna testing but are curious to know more.
![]() This section of the site is intended primarily to provide information to the latter group. It doesn't pretend to be a learned dissertation on genealogy dna testing. It is merely a primer. It is aimed at the amateur family historian who is curious about what this scientific development might offer his/her research and wants to know what is available and what to consider before deciding whether or not to proceed with a test.
Why bother with genealogical dna testing? If you've already unlocked a fair few generations of your ancestry, dna testing may seem an unnecessary luxury. Or, depending on your approach to research or your level of curiosity about your genealogy, dna analysis may offer just the answer you've been waiting for. Any of the following reasons might make you consider the cost of genealogy dna testing to be within your budget.
If you've been a family historian for any length of time, it's possible you've been contacted by someone, a stranger, who shares your surname and wonders if you might be related. After a few cursory questions and answers about immediate family and/or a generation or two of ancestors, both parties usually come to the conclusion that they are not related.
This is where surname studies come in, because Y-DNA (see below) is passed intact, along with a surname, down the male line. Surname studies and Y-DNA are, therefore, natural partners in the genealogy dna testing portfolio.

Myths about genetic dna testingYou've probably read or heard about dna paternity tests in the salacious 'celebrity' pages of tabloid newspapers and magazines, or about dna forensic evidence solving heinous crimes. Genetic genealogy is altogether milder, and perhaps less specific. For example, genealogy dna testing won't tell you about your family's predisposition to certain medical conditions. Being still relatively new, there remains a certain amount of misinformation floating about. For example, blood tests aren't necessary, nor, if you're a little 'short on top' do you have to give up a precious lock of hair. It's all done by mouth swab... quick, no messing and painless. Genetic dna testing is sometimes seen as an alternative to thorough genealogy research. Let's be clear:
Risks of genetic dna testingWhile none of the commercial firms currently offering genealogical dna testing is geared up to provide genetic medical information (ie a propensity for certain diseases), it is possible that some types of dna tests could inadvertently detect certain diseases or infertility. A more frequent detection is of a 'non-paternity event' ie illigitimacy. Within surname studies, this can often be pin-pointed to a particular generation, and has the potential for upset. Your view of your ethnic heritage may be challenged. Are you ready for that?
Surname group studies see the most widespread use of genetic dna testing.

But there is a chance (and, with some names, a likelihood) that you and this stranger are indeed related. The problem is that the 'common ancestor' is further back in time than your combined genealogical research can take you.
