[1][2] She was the first woman president of the Royal Institution of South Wales (RISW)[1] and a Fellow of the Society of Antiquaries.

She resigned this post when she married her first husband, Percy James Williams, a local architect.

She became the Honorary Curator of Antiquities, and in 1936 compiled an accession register of all the objects, information from which is still used today.

It was during this time that she first worked with W. F. Grimes who was assistant keeper of archaeology at the National Museum of Wales.

She was to excavate archaeological sites before they were developed for defences or military instillations, again working alongside Grimes.

From there she began her excavation career in London and south-east England, working alongside many notable archaeologists of the time including Glyn Daniel, Dame Kathleen Kenyon and Sir Mortimer Wheeler.

The unexpected discovery of a bust of Mithras on the last scheduled day of the excavation generated considerable press and public interest, debates in Parliament and discussion in the Cabinet.
