Hi Andy
Thanks for that information.

I don't have anything on this Alexander excepting that he was Niel's father, so this is exciting stuff for me...most times I have seen his name it has been spelled Niel instead of Neil...maybe the census enumerator wasn't sure of spelling!

I am unsure what is meant by N.B.L.W as in your quote: '16/10/1787 Alexander Dingwall, a single man in Craigiemhulin and Mary Sutherland in Crospie, a single woman (N.B.L.W), Alexander'. Sounds like some sort of League of Women.
Also not sure, was there something after Alexander in this quote? Was this date that of an earlier marriage, or of a child born to Alexander and Mary? And was that child also named Alexander? You don't say...maybe that information isn't there for you to know what it is about anyway.
So many questions, so sorry to not quite understand what is meant here. Just hoping you can enlighten me anyway, or someone else may understand better than I.
Thanks muchly
