[Ger-Poland-Volhynia] DNA testing

[GARY.RUPPERT at comcast.net]

The results of DNA testing whether mitochrondial or haplotyping are very interesting, especially in a specialized group represented by this mail list, I am wondering however how often these somewhat expensive studies have proven useful at either establishing or disproving a genealogy link to another individual and thus extending or pruning a line? Although knowing ancient origins may be of interest as the subject for a cocktail discussion,  if that is all DNA testing is able to provide at the moment then its utility is still limited. 



Have any of you had specific examples where connections were made or assumptions were disproved?  If so, were they something more than resolution of a question or paternity or did they make a major change in your research?
