gaelic pronunciation

[DWFII]

With regard to "tuatha"... one of the reasons I asked is that in Ireland is Castle Doe--the seat of the MacSuibhnes post Bannockburn, who ruled over the Trí Tuatha Thoraighe.

"Doe" (as in Castle Doe) is, I am assuming, pronounced "doh" yet the original Gaelic is "Caislean na dTuath". So how does "tuath" (pronounce "too-ha") become "doh" ?

How is 'cean' (head) pronounced?..as in Cean Mor (large head). I've read and heard pronunciations that go "kay-oon", "kay-uhn", and "ken."

"Ceann" is the Irish word for head, pronounced "kay-in".

You almost got it. "tuatha" is pronounced "too-aha", but "dTuath" is pronounced "doo-ah". So fom "doo-ah" to "doe", that's not a big stretch.
