Hi Athena GR
Thanks for info. I spoke with someone recently who indicated that the Pemrbroke cottages Shane noted on the OSI map recently were known as 'the Estate Cottages' locally? On the opposite side of the river down from the Vocational Tech are 8 cottages also named 'Estate Cottages'?
I've located a cousin who seems to have some information and whom I'm hoping to meet in the next couple of weeks re my gf Charles. I'll let you know if there appears to be any connection to your James Byrne, but at the moment it seems unlikely.
