Wow, now would "Foreign Connachta" be referring to the "more recent" entry of Conn's ancestors into Ireland compared to the other big celt migrations that were already there? That's fascinating.
There is a
Mac Guaire "Maquarrie" family in Scotland, specifically Ulva in the western isles. It appears that there were probably at
least two
Ó Guaire families in Leinster, one being mine in the Offaly area with a branch in Waterford and likely another with S. Leinster origins.
I didn't realize until very recently that the "r" was rolled:
https://www.teanglann.ie/en/fuaim/guaire which gave the impression "Goo-eh-deh", "Gwah-deh", etc. It's clear from all the odd spellings in the fiants, the english writer was unsure of what was even being said here.
Woulfe gives for Ó Guaire:
"Wexford-Waterford, Midlands; Originally from midlands" while MacLysaght says
"The original clan was located somewhere between Offaly and Meath". What appears to be a mac-alias, seems to have developed by the prefix
Mac Ui by this family. The earliest fiant in 1551 is "Mulmore M'Iguowde"
(Máelmuire Mac Uí Guaire). If I compare the other family in the area that I know did this
(Mac Ui Crosain) they are "Macicrosan" in the Kildare rental into the earlier decades of the Fiants and by c1580 "M'Crossan". So it seems very probable that many surnames that Woulfe and MacLysaght confirm as Ó-prefixed probably had "Son of the descendant of" branches that in modern times we mistake for just an alternate Mac-prefix, as their
Mac Ui generations were not recorded.
This would also explain something I found a while back that I thought was a transcription error:
F.Eliz.2682; Thady M'Y Leyne of Balymakernagh, Co. Waterford. One of John of Desmond's men. 5 May 1576
Mac Uí Laighin?
I figure there was at least another O/Mac Guaire family in Leinster for a few reaons. Not only the frequency of the given name in Leinster in the 8th to 11th centuries that probably spawned a family, but I have two Kilkenny "Gorey" men who are S7898, although I'm not sure of those SNP origins or if they're even NPEs or not. In modern times there was a large Gorey family around Thomastown but this is not supported by any Fiants. And as much as I've been trying to see if I could place the Ua Guaire who was
tigherna Ui Cuilinn (AFM1032) and slain by Ui Cennsalaig king Diarmat mac Mael-na-mBo, as potentially in Offaly, the Ui Cennsalaig had a Clann Guaire (confirmed in Rawlinson B502) and ruled several Ui Cuilinn kin groups in the region. This could probably be Diarmat mac Mael-na-mBo exercising authority on an insubordinate sub-chief in his rise to taking the Leinster kingship from the Ui Dunlainge in the coming decade. There are three Ui Cennsalaig kings in the 9th century with "mac Guaire" patronymics so the likelihood that this developed as a surname here is very good, and that the "Wexford Gorrys" that Woulfe identifies are not one & the same as the Midlands-Waterford Gorrys, and were probably the Clann Guaire of Ui Cennsalaig. Potentially the Kilkenny Goreys are not either of these families, and could even be anglo-norman
de Gaor, (Gore>Gorey?), however I haven't delved too much into it, but the Gore surname cluster is roughly in Kilkenny/Central Leinster.
