I had my mother and my father, both in their 90's, tested and also my Dad's y-dna test, which has been the most valuable for me. I've had mine done, of course, and my daughter's. I'm glad I had parents tested, as Mom turns up some common ancestors with matches a generation further back than I match to, if that makes any sense. So, through her, I can basically find matches a generation further back than I'd be able to match to myself, due to so many generations out. Definitely get your parents done before yourself! If you have them both, you don't really even need to do yourself, unless you're unsure they're your bio parents!
