The Crow/e families in the U.S.A. have been very active participants in the new science of genealogy by genetics. So far, the project has been running for eleven years and there are over 325 members. They have established a web-site which is linked to Family Tree D.N.A.
The American Crowes have distinguised seventeen genetic groupings, known by colours. The various branches are fitted into one of these when results come through from testing certain markers on the "Y" chromosomes of volunteers. From the results obtained so far, the "dark green" group of Crows, mainly descended from Charles Crow, who settled in Maryland in the 1680's, appear to be very closely related to "our" Crowes. In two cases, there had been no genetic mutation to differentiate their reading from "ours", despite the presumable lapse of some 300 years.
There appears to be a close correspondence between the Crowe genetic signature and that of members of theMaher or Meagher family, originating in the Barony of Ikerrin in County Tipperary, Ireland. This may be a better pointer to the immediate whereabouts of our family before they arrived in Man. Where matches are obtained with individuals of the same surname, however, because surnames have only been in use for a relatively short time, in genetic terms, and because of the large number of surnames in the database, the chances are very high that the genetic identity indicates a "close" family relationship - i.e. in this case that the Maryland Crows are indeed our distant kin, and share our McCraw roots here on the Isle of Man!
A detailed study carried out in Iceland, Norway, Scotland and Ireland showed that at the present time "our" genetic fingerprint was much more strongly concentrated in Ireland than in any of the other regions studied.

The Manx Crowes fit into the Haplotype R1b, generally understood to represent the earliest inhabitants of Europe. Later these lines represent the ancient Britons, and then their descendants, the Celtic inhabitants of Wales, Ireland, Scotland and the Isle of Man. Celtic culture in the British Isles split into p-Celtic [Wales and Cornwall] and q-Celtic. The Isle of Man was originally p-Celtic, and there is a Welsh prince, Guriat, buried at the Celtic monastic site at Maughold, which recalls this link.
Later cultural influences and population movements brought about the dominance of the q-celtic language and culture on the Island. The Manx Gaelic language is closely related to Irish and Scottish Gaelic.
Therefore it is possible that our surname reflects Irish ancestry and cultural links, while the male ancestral line may eventually be traced back further to link up with Welsh lineages.
