Elizabeth was married to the poet E.V. Lucas and was mother to Audrey Lucas. One of Audrey's poems is featured in some of the Exhibitions and in Volume I of Female Poets of the First World War. Audrey was at Downe House School in Kent during WW1.
With financial backing from author J.M. Barrie, Elizabeth Lucas took over a chateau at Bettancourt in the war zone on the River Marne in northern France during WW1. She set up a refuge for orphaned and displaced children. Her daughter helped out during the school holidays and when she left school, worked as a nurse in Paris.
