She attended Cleveland Street Public School and Mis Somerville's Ladies' College and worked for the Liberal and Reform Association.

She became general secretary and organiser of the Australian Women's National League in 1911 before returning to Sydney in 1913 to work for the Liberal Association of New South Wales.

On 14 March 1917 she married Andrew William Glencross at St Stephen's Presbyterian Church, moving to Stawell later that year and vigorously supporting the pro-conscription campaign.

Glencross made accusations of political bias but an investigation by Frank Forde found her claims to have no foundation.

[3] Glencross presided over the Good Film and Radio Vigilance League of New South Wales but was left financially insecure by her husband's death in 1930.
