Hi Rose UK
From
http://www.askaboutireland.ie/griffith-valuation/index these are in date all about 1863
CARVIL PATRICK DOWN KILBRONEY ie BALLINCURRY townland
CARVILL HENRY DOWN KILBRONEY LEVALLYREAGH townland
CARVILL EDWARD DOWN KILBRONEY ie MOYGANNON townland FRANCIS CARVILL & SON DOWN KILBRONEY ie NEWTOWN townland
cut & paste details removed- please use above link to search Griffith's Valuation See Ros Davies parish map for kilbroney it shows the townlands of LEVALLYREAGH and DRUMSESK are neighbours and the homestead might be in the border region.
Griffiths valuation website has the ordnance survey map of about 1860 marked up with each properties border So it will take patience to find on the map, I have just done it its entrance to the farm buildings and adjoining fields is almost opposite the gate lodge to Knockbarragh Park in the adjoining townland of Knockbarragh/Ballyagholy. The river Moygannon looks as if its on or within the property. One might see it on Google maps
Good luck, this could be your henry
