[4] She married entrepreneur and inventor Ralph Lucas in 1903,[5] and their son Colin became a noted architect.
Lucas gave up composition for over 25 years after she married in 1903 and had a family (two sons and a daughter), but returned in the late 1920s, when the Bournemouth Municipal Orchestra performed her Rhapsody (1928) and Fugue (1929).
[12] It was later orchestrated as the Circus Suite, which was conducted by Henry Wood at the Royal Albert Hall on 4 July 1942, giving Lucus her Proms debut at the age of sixty.
[13][14] Lucas had a special affinity with the clarinet, and may have encouraged her niece Pauline Juler (1914-2003) to become a professional clarinetist.
(Juler later became associated with the clarinet music of composers such as York Bowen, Gerald Finzi and Howard Ferguson).
[20] Participants in these gatherings may have included friends such as Paul Nash, Alain Daniélou and Edmund Rubbra.
