Hi,
I know it's a while since you posted your enquiry. I know Warrenscourt.
There is a relly nice wood there and a big old house. If you google Radleys of Cork on that site there is a section on the Warrens of Warrenscourt. It contains a lot of information on the family.
Also there is some information on Warrenscourt forest in the
www.coillte.ie ( Irish forestry services website).
Good luck with the search.
