I have seen a few possible connections which could fit with my I4 mtDNA Haplogroup. A Scottish-Scandinavian connection is most predominant one so far. What I have been able to ascertain it is an old haplogroup with very small and geographically diverse population. Considering where it originated, the idea that it might connect with "gypsies", Jews or some other Eastern/Central European groups does make sense.

My direct mtDNA line is: Robinson (Scot-Irish), Yates (Scot-Irish), Eller (German), Miller (German), Triplett (English), Gray (English), Wells (English), and Bowers (English 1735).
