thanks for that Jim
I had seen the message from 2000 and it sounds intriguing - maybe there's a story there to rediscover. I'm hoping that someone in the area around Rathcormac may have a little more information.
Based on your pointing out of Readoty in Co. Waterford (and I'm in Co. Waterford myself!) I discovered from Canon Power's Placenames of Decies (1908 & 1952) that it means 'burned mountain plain'. This obviously gives a good idea as to where Redota might be found... Thanks for your help Jim
