If she's the right Jane, in 1871 she is head and a charwoman at Hill PLace Edinburgh. No other family listed at all. Alexander may be a boarder and apprentice plumber but as it's at a boarding house, there are loads of other people and difficult to be sure. So that would mean that John died between 1861 and 1871. You should be able to track this down on Scotland's people and you would then get his parents details too.
There is a John Thomson born in 11 December 1815 in Lesmahagow to James Thomson and Jane WIlson. Possibility but a common name so you really need to track down that death record.
