I have found her on census records up until 1861 where she is with her family at 19 Albert St, Govan. I don't think she was ever married to David or the father of John and James Mc(g)rory
David Balintine 55 born Stirling (although I think he was born at Perth)
Christina Balintine 41
John McRory Balintine 15
James McRory Balintine 9
Christina Balintine 1
Margaret Adams 31
James Adams 4
David's death in 1867 was registered by a neighbour and in the 1st column it says widower of __________________ blank! I think David may have been married before.
Her daughter Christina married for the second time in 1886 and according to that Christina senior was still alive.

I have tried all sorts of permutations of names to find Christina's death but no luck.
Hopefully fresh eyes will make it simple.
Regards,
Annette
