Sorry Annette - had changed the Title but not the name....
Thanks for pointing that out about the birth place- I have just looked back through my census information and his birth place is not given in 1861, obviously I misread the 1841 census.
I do not have the census for 1851 either I have realised, so will look for it now, but if anyone fancies looking too then that would be great.
Census ref for 1861 is RG9/3763
I also don't have Alexander's death, but it looks like he died between 1861 and 1871 as Agnus lives with daughter Agnus in 1871 and is widowed.
Thanks - sorry for being so confusing!
