Hi shanew147
Thank you very much for all your help!
As I'm only new to researching my family there is so much i have to learn.

The area I'm searching for is in the parish of Kilquade. While i have found birth certs for some of Catherines children there are no matches for either of her marriages to John Heffernan or James Sinnott in this parish.
It just may be possible that not all of the records for this parish are on the IFHF site.
The baptism cert i have for John Heffernan 02/05/1860 shows that his parents, James Heffernan and Mary Elliot lived in Coolroe, Carnew, Co. Wicklow.
I'll start the search again and widen the time frame and try different spellings of names etc... If that fails to show up anything I'll use that microfilm Pos.6478 and go check it out in the NLI.
Much appreciated
Wicklow way
