Hi again, Heather.
I believe I have found Samuel Lawson on the 1901 census but haven't been able to find Anabella yet. She should be in Scotland I would think as their marriage date in Stirling was 16 Apr 1901 which is only a couple of weeks after the census was taken although I suppose it's possible she could have been en route. Samuel was living with his mother at Milton, St Ninians, Stirlingshire as follows:
Margaret L Lawson, 68, head, born Glasgow
Samuel Lawson, 28, son, born St Ninians, Stirling, coal miner
James McNeil, 16, grandson, born St Ninians, Stirling, coal miner
Agnes Lawson, 22, granddaughter, born St Ninians, Stirling
Minnie Lawson, 23, visitor, born Ireland, linen winder
I also believe I have found Sarah Jane Laurison but she was in Ireland and I'm not sure whether she was the daughter of Anabella. The National Archives of Ireland has a searchable database for the 1901 and 1911 census. Sarah Jane is listed with John and Sarah Jane Laurison in Laurelvale, Mullahead, County Armagh but as their neice, not granddaughter. Here's a link to the census image:

She is listed as "daughter" on that one but there is another daughter listed named Sarah Emily so something doesn't quite add up there. Here's the image for that census:
