My wife is a Carson & descends from the line of William Carson, b. abt. 1763, Ballybay, Co. Monaghan, Ireland. This line most probably appeared in Co. Monaghan in the late 17th Century, possibly descending from another William Carson, born about 1655 in Scotland. Dumfriesshire is suspected, as this is a reported origin place of the surname Carson, and variants. This Carson line appears in entries at Ancestry.com (e.g. Kahlstorf Family Tree), and in “The Carsons of Ballybay”, by David Melville Carson. Go to http://contentdm.lib.byu.edu/cdm4/search.phphttp://contentdm.lib.byu.edu/cdm4/search.php Type “The Carsons of Ballybay” into “The exact phrase”. Page 19 in the Appendix discusses migration from Scotland.
We now have results on yDNA of one of my wife’s brothers. We were expecting a haplogroup indicating either Viking or Celtic ancestry, but instead were gobsmacked to discover membership in Haplogroup J2, which is somewhat unusual in Britain. But not in Italy (or other Mediterranean areas). The first thing that came to mind is the assertion that the surname Carson derived from an Italian guy named Corsini. Senior Corsini settled in current Dumfriesshire in the late 13th Century, having come to “superintend the erection of Sweetheart Abbey and Devorgilla’s Bridge over the Nith” www.electricscotland.com/history/dumfries/history20.htm
Another explanation would be that the yDNA of my wife’s brother is not the same as that of his reported forbears from Scotland. Prominent genetic genealogist Charles Kerchner indicates that in addition to ancient migration, a “…more recent mode for J2's entry into some parts of Europe from the Mediterranean areas could have been the Roman Legions and Roman settlements.” www.kerchner.com/haplogroups-ydna.htm
Ponder this: “The fact that all three groups--E3b, J2, and Haplotype 35--have a similar origin in territories of the Roman Empire, and occur at comparable frequencies in parts of Britain with a known history of Roman settlement, suggests that they arrived in Britain through the same means.” Dumfries (a bit north of Hadrian’s Wall) is mentioned in the same paragraph as this quote. http://freepages.genealogy.rootsweb.ancestry.com/~gallgaedhil/haplo_r1b_ht35_analysis.htm#ht35_fourhttp://freepages.genealogy.rootsweb.ancestry.com/~gallgaedhil/haplo_r1b_ht35_analysis.htm#ht35_four
Well, we certainly have some far-out hypotheses to consider. More adventures in ancestral research.
