She was born Emma Trina Cox on 3 March 1895, in the Lower Bebington Urban District (i.e. not Bebbington), on the Wirral Peninsula and grew up around Birkenhead. She trained at the Laird School of Art.

In about 1945, Trena Cox moved to 96 Watergate Street, Chester, which remained her home and, at least later, her studio, until she retired in 1972 (at the age of 77) and died, on 11 February 1980 (not in 1977, as frequently quoted).

Document 11: British Isles: The demographics of the British Isles today are characterised by a generally high density of population in England, which accounts for almost 80% of the total population of the islands. In elsewhere on Great Britain and on Ireland, high density of population is limited to areas around, or close to, a few large cities. The largest urban area by far is the Greater London Urban Area with 9 million inhabitants. Other major populations centres include Greater Manchester Urban Area (2.4 million), West Midlands conurbation (2.4 million), West Yorkshire Urban Area (1.6 million) in England, Greater Glasgow (1.2 million) in Scotland and Greater Dublin Area (1.1 million) in Ireland.[citation needed]
Document 12: British Isles: The population of England rose rapidly during the 19th and 20th centuries whereas the populations of Scotland and Wales have shown little increase during the 20th century, with the population of Scotland remaining unchanged since 1951. Ireland for most of its history comprised a population proportionate to its land area (about one third of the total population). However, since the Great Irish Famine, the population of Ireland has fallen to less than one tenth of the population of the British Isles. The famine, which caused a century-long population decline, drastically reduced the Irish population and permanently altered the demographic make-up of the British Isles. On a global scale, this disaster led to the creation of an Irish diaspora that numbers fifteen times the current population of the island.
