Thanks All,
The reason for the hunch about Bridget being protestant is the surname of Law. They appear to be from Scotland and predominently protestant. Presbyterian would be a good possibillity for a Scotsh/Irish familiy moving from Scotland to Ireland at the turn of the 19th century I would think. I have no idea how to explore Presbyterian records though.
I have all the records from Scotland and also from England when they moved there a decade later. I have a great deal on the family and descendants past their time in Ireland. Not many stones unturned there...it's the "dark ages" in Ireland that cause me grief and keep me from learning about the Law family.
The record for Winifred Moore is definitely on my radar but, as she wasn't with them later in the census and I couldln't find any deaths, I could never confirm Winifred born in Cork was theirs. However, the survey was in Cork during that time so it is not impossible to imagine. That would make Denis' mother's name likely Winifred if that baby was theirs. There is also a bastard "Magdalen" born to Denis Moore and Bridget "Lay" in Mountrath in 1836 that I cannot rule out as a possible first born.
In the 1851 Census in Edinburgh, the family was living with Denis' brother Anthony 20 y and nephew Fenton 20 y. I've learned a great day about Anthony, another surveyor, and his descendants. Could never confirm which Fenton Moore (several in England where they all moved and assumed he moved too instead of returning to Ireland) was this man in later years. Would be good to know who his father/Denis' brother was.
I feel like I have so many things. There must be a morsel somewhere that would lead me backward to where I need to be if I just looked at it diffierently/correctly.
