Talk:Ó Duibhgeannáin

Name variations
"Deignan" is one. Mine, actually. Not sure what I can use to show notability or satisfy WP:V, though.12.53.10.226 (talk) 03:33, 28 January 2011 (UTC)

DNA Results
Are the Ó Duibhgeannáin Ui Neill? I see that Deignans and some Duignan has the Ui Neill signature, however not all. Suggest two families with this surname?

I would suggest that this is spill over due to the mixing up of families. the Duibhgeannain would have had foster children from related and non-related ruling clans. An indicator is the other families of the same z253 haplogroup who were absorbed by the O'Neill as the O'Neill gained power throughout the midlands. These would be Mongan and Berkery, the former which were erenagh's like O' Duibhgeannain, and the latter which were Ollamh's like the O'Duibhgeannain. Here we see hereditary occupation lined up with DNA and familial relationships. O'Farrell are also z253.

In the Royal Society of Antiquarians of Ireland Seventh Series Volume 11, No 3, there is mention of the progenitor of the Deignan /Duignan clan. The area of Tethba it seems was more of a confederation than a monolith, with different lines taking power at different times.

The Ui nDuibcind (clan name early spelling) appear in the annals after Tethnba was subjected to heavy Danish attacks. Early ruling families were devastated. The first mention in 972 is of the killing of Donnchad Finn, cousin to high king Donnchad Donn, by Adgha Mac Duibhcend. This Duibhcend is the “black haired chief” from which the Deignan/Duignan descend. He along with other family members are buried at Clonmacnoise. O’Rourke conquered the area in 1070. Clonmacnoise was a major center for learning in Ireland and the Deignans were a preeminent scholar family for centuries in Ireland co-authoring the Annals of the Four Masters and several other annals which leaned heavily on the Book of O’Duibhgeannain

In Cronnelly’s “History of Clanna-Rory” He quotes O’ Dugan as stating that the O’Ferrall’s of Conmaicne were styled Lords of Forthuatha Laighean of N. Leinster and Princes of Teffia (Tethba). In my mind this confirms the N. Laigen association with z253 S845 where we also find the Berkery pedigree as well. The Forthuatha Laighean were mercenary tribes of the Laigen. — Preceding unsigned comment added by 98.150.196.164 (talk) 00:15, 28 November 2020 (UTC)
