In 1932, the Queensland Society for Crippled Children was established to care for children with severe physical disabilities arising from the polio epidemic of 1932. In September 1932, Marchant donated his home "Montrose" and its 5 acres of gardens at Taringa to the society to establish an institution for the care and treatment of the children. When the number of children needing care became too many to be accommodated in Montrose, Marchant purchased a property at Consort Street, Corinda as a new larger facility which continued to be called Montrose (which is still in use for the care of disabled children in 2015).
