This morning I heard from Gerard Carden of Glasgow, whose ancestors lived in
Co Sligo, Ireland.
It is a fascinating result. It differs from the seven identical Cheshire
Group results only in respect of one of the ten markers (DYS 390), but shows
21 repeats for this marker instead of 24. Oxford Ancestors say a difference
of 2 repeats in a single marker is commonly caused by a single mutation.
Their comments on a difference of 3 have been requested. Subject to this, a
preliminary conclusion must be that the May-Sligo Cardens are the descendants
of a Cheshire Carden who emigrated to Ireland many years before the one who
emigrated in about 1655 and founded the Cardens of Tipperary.
It also suggests that Thor, who has 23 repeats for this same marker, may come
from the May-Sligo Group rather than directly from the Cheshire Cardens who
remained in England.
I will soon send Trish the details to up-date the report on her web site, but
could not resist sharing this result with you immediately!
