The grandmother of Aldous Huxley, Henrietta Anne Heathorn, was 'a brewer's daughter born in the West Indies'. 'In July 1847, shortly after arriving in Sydney', Thomas Henry Huxley (q.v.) met 'Nettie' who was 'keeping house for her brother-in-law William Fanning.' Impulsive by nature, 'Huxley became engaged to her on their sixth meeting'.
Three years later Thomas Huxley departed Australia, arriving in England on 23 October 1850. Due to financial considerations, 'Huxley and Nettie (who remained in Australia)' had 'resolved not to marry until he could pay his own way ... After an eight-year engagement Nettie arrived in London in May 1855; she and Huxley were married at All Saints' Church, Finchley Road, on 21 July.'
