Though I'm not quite as big a fan of mtDNA testing as Ann, I definitely agree that they can be a very useful tool in specific circumstances. They are also the only game in town when it comes to understanding our deep matrlineal ancestry, which I personally do find very interesting. That said, I think their value is often overestimated when it comes to general genealogical use and this can sometimes have the negative side effect of leading people to bark up the wrong trees (bad pun shamelessly intended). For instance, I think the most you can derive from your test is that your very distant (1,000's of years) matrilineal ancestors were of European origin, anything more than that would be highly speculative and potentially misleading.
In most cases, and almost certainly yours, people are far better off focusing their efforts and resources on auDNA test results. Particularly when searching for close relatives, such as parents or grandparents, few tools can match the value of an Ancestry DNA test, the results of which can then be uploaded to FTDNA, MyHeritage and GEDmatch, all of which can provide much better tools for analyzing your matches for a nominal fee. Another great resource are the Adoption Angels here on Wikitree. And if you'd like any help with your auDNA just send me a PM and I'd be happy to do what I can.
