Catherine, A birth certificate would not be available prior to 1864. I also assume that Glanmore should be Glanmire because I cannot find Glanmore listed anywhere. If it is Glanmire Roman Catholic christenings only go back to 1817. For Church of Ireland see the following website http://www.cork.anglican.org/Parishes/Cobh&Glanmire.html. Since the church in Glanmire was consecrated in 1786 there might be a chance they have records though they were not required until 1837 or the Cobh Heritage Center may have already transcribed them.
