Morning Roger.
Many thanks for your quick reply and all the effort and information you supplied. I have the majority of this work done and have got as far as (with the help of Fr.Egan P.P Knockavilla) the baptism of William on 8/6/1838. So I'm looking now for any info on John Doherty whom I found in the 1850 Griffith Val. Mary is harder to find as according to Fr Egan there is no record of her baptism or her Dad, Michael. Fr Egan thinks William and Mary were married in the church at Ruan near Ballintemple cemetery.
Fr Egan also says that William was from Lacken(parents John Doherty/Alice Navin) also in the Parish of Donaskeigh and his Godparents were John Austin and Mary Navin. I have tried all the ususal research sites and have hit a brick wall.
Thanks again.
Gerry
