I am researching Patrick H Malone,born in Ireland March 30, 1828, son of John Malone and Nancy Kennedy also of Ireland. I have found census and death certificate references for where he is from in Ireland but just can't put the clues together. A son says on a census Patrick is from Northern Ireland. Another son says Donegal, Ireland. A death certificate lists father from Bitford, Ireland.

Can anyone shed some light on these clues?
