Hi Mark,
I have done a search and the only John McAuley I can find is in Whitburh, Linlithgowshire. Quite a few similarities, but could be the wrong one. I could not find a marriage cert so far.
In 1841 at Longridge Whitburn Linlithgowshire
John McAulay 34 b 1807 Glasgow Occ – Weigher of Iron Stone
Margaret (Forrester) McAulay 32 b 1809 Bathgate Labourer
Margaret Ferguson Macaulay 10 c 07 Jun 1840 Whitburn labourer
Isabel (la) MacAulay 8 c 11 Sep 1842 Whitburn
John McAuley 5 b 1846 Whitburn Scholar
George McAuley 3 b 1848 Whitburn
Alexander McAuley 1 b 1850 Whitburn
Francis MacAulay 14 c 05 Feb 1837 Whitburn, may have died before 1851 census
As you do not mention Isabel (la) or George, they maybe young deaths, also
Next census I see them in is 1891 when John McAullay is 84 a retired pitheadman and Margaret is 81 are living at Bentfoot Cottage, Whitburn.
