Cooke-Cull family

Am seeking any information on the Cook/Cull family. Father's name is Maurice Cooke (Cook). Mother is Mary Cull. Two of their children were baptised in the Ballyagran and Co in 1842 and 1843 before they immigrated. I have no information on the Cook or Cooke family. Thomas Cull and Bridget Cull were sponsors for the baptisms.
