One of my ancestors John Andrew Cobbe married an Anne Ormsby 9/11/1876. His father John Cobbe married a Mary Kerwan or Kirwan 7/2/1831 [parish St Michaels. This John Cobbe was born 1806 and died aged 68 on 30/4/1874. Both John Cobbe's were at one time church sexton in C/Ireland parish church. Any info would be appreciated.Also Robert William Cobbe born 10/3/1879. Birth is not registered in PRO in Dublin and cant find parish entry. Any ideas?
