Hi Bessy,
I did eventually get to read a copy at my local library, but there wasn't quite as much information as I'd hoped. My mum was born in Cullybackey, and apart from me, my family all still live in N. Ireland.
The family I'm researching is the Given family. Thomas Given, the Ulster Scots poet was my g g grandfather (he lived in Dunnygarron). I know that his father was James Given, but I cannot get any further back. There is a link to Ayrshire and the story of how Markstown got its name (via Givens and McKees), all of which fascinates me. If any of this is familiar to you I'd be glad to know

Thanks for getting in touch, Peter
