Hi Greg, www.nationalarchives.ie for Griffith Valuation records mid 1850's there are some entries for a Patrick Conway namely in Corkbeg Village of Gyleen, Ardra, dont think the records in Rostellan are relevant. Unfortunately these records only give details of a person in residence in a locality, amount of holding & rent paid, doesnt give info on family members. No records showing for Patrick on Tithe Applotment records 1820's.
I know some Conway people from the area & will make some enquiries - one came from Ardra which is location of one of the Patricks on the griffiths valuation. Have looked at www.historicgraves.ie but the only Patrick recorded died in 1937 which is too late. If you look at the grave site, the cemeteries to check are Corkbeg, Aghada Old Cemetery. Will revert back to you if I am able to source any more info.
Regards, Frances
