Welcome to Ireland Reaching Out!
Nutgrove/Feebrack townland is in Tynagh civil parish and the RC parish would be Tynagh. When I searched for a marriage record for this couple, I located an 1855 marriage record at Carrabane RC church which is a good distance from Tynagh. When I search for baptismal records for children of this couple, they were in Carrabane parish not Tynagh. When I searched in Tynagh, I did not find any records.
For other readers of this message when did your Thomas Burke and Johanna Moran marry and what were the names of their children. Thanks!
