TAF, My mtDNA was tested at 23& for a value of haplogroup U a very ancient type, At Ancestry, haplogroup H. At FTDNA, type H2, etc. Apparently, FTDNA revised their original agreement with type U based upon later discovered SNPs, as Mitosearch has a few matches claiming to be U4 with testing done by FTDNA, whereas FTDNA now has many matches for H2 etc., apparently based upon newly discovered SNPs. So what is the relevance? The body of St. Luke in Padua, Italy tests H2 etc. This is a worthwhile comparison, as are those of Bourbon and Czarist monarchs, also type H. With regard to specific ancestry, I am totally in agreement. Sent from my iPhone
