James Grierson Clingan/Aitken/Dawson

[Clingan]

Clingan
Can anyone help please.
Unable to find death details of Rachel Clingan, wife of James Grierson Clingan who died 1934 at Kirkcudbright.
Her MS was Aitken.
She was a widow with the married name of Dawson when she met and married James (a widower) in Dumfries where they lived for some time.
Have all other details but still not able to find her, even after searching both
statutory deaths for Dumfries, Kirkcudbright and all other areas. Not mentioned on family stone at KPD.
Any ideas of where to go next?
Thanks
Ian
