I Am Researching the Sweeny Sweney Sweeney Family of the Seagoe Area of Armagh

My great grandfather Robert Sweney born b1844 in Portadown came out to N.Z. for the gold rush in 1870. His parents were
Anne Reid 1810 - 1863 who came from Scotland and John Sweeny. Robert Sweney was christened at the Church of St Gobhan on 3 Apr 1845.
I know nothing else about the family and wondered if someone might be able to help.
