Splendid. I think I've got a good enough grasp on the peoples that lived in the area during my period. Since I don't have much of a disposable income at the moment, I decided to check my local library for that book you mentioned. They didn't have it so they're checking other libraries to see if I can get on on intra-library loan.
In a very related note, you may have noticed that my handle on here is Maghnus Ó Sionnaigh while just underneath it gives my full name as Shawn O'Hara. That's because my SCA persona's name is Maghnus. Just a name that sounded really cool to have and so far I respond more to Maghnus than Shawn these days. Sionnaigh was just something I found while browsing the St. Gabriel website for bynames. It translates to "The Fox." Again something that turned out to be personal flavor.
So trying to make a long story shorter, I found a pretty good read on the history of Ireland from the BBC website. It mentions all the events in more detail than I've thus far looked for, which can be a good thing, and in my case was awesome. I found what seemed like an obscure reference to the killer of Hugh De Lacy:
"Once a territory had been pacified, it was secured by stone castles. The site had to be chosen carefully, with solid rock as a stable base for preference. The largest of all was Trim Castle, built by Hugh de Lacy, extending over three acres though it may not have been complete before this Lord of Meath was murdered in 1086 by an Irishman, known as ‘The Fox’."http://www.bbc.co.uk/northernireland/as ... ic31.shtml
I thought this seemed too good to be true, so a search of Wiki on De Lacy revealed not an article but the following information: "Hugh de Lacy was killed while supervising the construction of a Motte castle at Durrow, Co. Offaly in 1186 at the instigation of Sinnagh (the Fox) and O'Breen (see Annals of the Four Masters, 1186.5)"
We all know how hit and miss Wiki can be, but the reference to the Annals of the Four Masters was like gold for me. Okay, okay, long story even shorter, I found more credible sources that have basically exploded information on the entire "Fox" clan/sept/chief. Up to this point, my entire basis for research was a made up name and a desired date range based entirely on my research of armor developments (I am an SCA heavy fighter after all), but now that the possibility that I actually have a specific place
with a pretty detailed social dynamic
is just more that I could have hoped for.
I am no wondering if anyone can shed any farther light on this clan. I'd list what I've read, but my knowledge is just too sporadic to write coherently. All I can say with some modicum of certainty is that they were heavily populated in County Westmeath and fought heavily against the English. Any additional information is welcomed with open arms.
