Two items of information from SP:
1)Death cert of Winifred Smith 7/3/1946 daughter of Henry Smith and Elizabeth Rooney or McKay of 34 Meal Vennel Perth,and
2)Death cert of Elizabeth Smith died 1974, aged 61, Martha Street Glasgow.Other names Rankin, Rooney.
Access to the latter cert is restricted so you will need to send away for it.
Hope this helps
