Gleeson,Mellerick

Looking for my roots and it all seems to point back to Ballymacoda area in Cork, my 2GG was a Micheal Gleeson born 1832 in Cork, baptised 03/06/1832 in Cobh parish sponsers David Hayes,Catherine Sullivan, Married to Catherine Mellerick 08/02/1855 at Ballymacoda. Sponsers John Kirk, Jehr Mcgrath. Children are Johanna 27/02/1856 sponsers Muarice Mellerick Joan Gleeson, Patrick 02/01/1857 sponsers Abby Mulrick Pat Finn, Hannah 25/09/1859 sponsers Mathew Mullin Mgt Gleeson. Catherine 25/08/1861 John and Ellen Melrick, Variations of spelling of Mellirick. Emigrated to Australia, arriving Melbourne 11/06/1863, have the details of both Gleeson's and Mellirick's in Australia, its the start of the tree I am chasing, Michael's father could be a John Gleeson who married a Johanna Walsh, that's all I have any help would be greatly appreciated....Peter
