Henry supposedly married Hannah Passer/Passen in 1804 when he would have been 18 years old. The only recorded children were born in 1815, 1816 and 1819 when his wife then died, presumably in child birth or shortly thereafter.

"Henry was 32 years old when he and his wife Sarah aged 26, with their children, Samuel (5), Hannah (3) and George (1) plus Rhoda* came to South Africa as part of the Bradshaw Party of 1820 Settlers. Most of the party came from Cam, near Dursley, Gloucestershire and had been recommended and sponsored by the Cam parish authorities who were anxious to relieve the parish purse who were 'overburdened with poor'. The party sailed from Bristol in the regular transport ship "Kennersley Castle" on the 10th January 1820 and arrived in Table Bay on the 29th March and Algoa Bay on the 29th April 1820. The party was located in Albany on the Torrens River and the location was named New Gloucester."
