Hi Lynne,
My records show Thomas, son of James and Margaret was baptised on 29 October 1780 in Marown and married Elizabeth Moore in Lezayre on 13 September 1803. James and Margaret originated from Marown but moved their family to Lezayre some time after the birth of their last child, Charles, in 1791 - although his baptism is registered in both the Marown and Lezayre parish records.
Hope this helps!
