What I posted was a link to show what church records are available as far as baptisms, marriages, etc. Civil registration of births started in 1864. The microfilm is at PRONI but not online.
shows a Sarah Langhland as 10 (and the person thinks its a bad transcription, that it should be Samuel who would be 10 in 1861.    The next person is my grandfather (W J Langhland)   I have today written to Ancestry to see if it can be proven or fixed.
The census image should be in Scotland's People database which would show what is actually written rather than Ancestry's transcription.
It should, but I can't find it.   I have written to them to ask if they can find it, as all the details are on it.

Just found some more notes of the 1861 census, but I dont have a copy of it, and I cant find it on Scotlands People
1861 Census of Scotland
Moncrieff St
William Laughland H Married 33 Miners Labourer
Jane Laughland W  Married 26
Samuel son 10 scholar
William John Son 2
George Laughland Son 6 months
Here, William is 33 and a miners labourer.
So it is William and Jane Grieve Loughlin who are your direct ancestors and their eldest child William John?   Then back to Ireland and  William's father William and his wife Jane Stewart.  Samuel, the son of William and his first wife Elizabeth who died in 1854, would be the half brother of William John.  And a step  gt uncle? Is that your reading of it? [/size]
  Correct, Not sure who is the step gt uncle of who though.
That's up to date I think, will check and see if there are any more questions to be answered.
