Sorry for delay in replying, been away. Yes Im female but unfortunately nobody else in the family will take it. Would it count if my son did the test? Its my side Im interested in though, not his fathers side. Thankyou.
Your son could take a Y-DNA test but that would only be helpful if you were interested in learning more about your son's paternal (ie, surname) line.
As a female you can take a mitochondrial DNA test which will tell you about your direct maternal line (your mother, your mother's mother, your mother's mother's mother, and so on) or an autosomal DNA test which will give you matches with genetic cousins on all your family lines going back for about five or six generations. The mtDNA test is more of a deep ancestry test which will tell you which haplogroup (clan mother) you belong to. Autosomal testing is a matching game. You can go on a "fishing expedition" to see what matches turn up but because of the large US bias in the databases the test is best used if you have a particular hypothesis to test, which would require testing other cousins for comparison.
To understand how the tests work you might like to look at these beginners' guides:
