As a great believer in looking everywhere, as there was a hint of artistry, I looked in my copy of "British Artists 1880-1940" and there are these entries:
SMIETON, Mrs. J. P. Exh. 1880
Panmure Villa, Broughty Ferry, N.B.
RSA 2
SMIETON, T. A. Exh. 1883
Panmure Villa, Broughty Ferry, N.B.
RSA 1
RSA 1 means exhibited one picture at the Royal Scottish Academy exhibition in 1883.
