Hi Ray, I found 2 Smoothy in Corowa RC cemetery.
Bridget died 18 Jul 1938 aged 76yrs and her husband
Martin William died 8 Sep 1927 aged 63yrs.
Bridget died at Tocumwal, I think that is where the family lived as I found a Thomas Smoothy was born there in 1896 and he died in Albury in 1952 but not buried in Albury.
I hope this helps your research
