He married Susanne Collins (c. 1834 – 14 April 1910) on 10 May 1855 at
Bowdon near Manchester. The couple moved to
Collingrove, in Australia, later that year. Country life did not agree with Mrs. Angas however, and on their next visit to England, she remained there, and for six years her husband lived alternately there and in South Australia, supervising his pastoral interests. A son
Charles Howard Angas was born at his grandmother's house in
Upper Clapton, England, on 21 April 1861, and his sister Lilian Gertrude Angas on 13 December 1862. In May 1863, John and Susanne Angas returned to South Australia on the steamer
Pera, with their two infant children. The family was in England again in 1879 when news of the death of John's father George Fife Angas was received, and they immediately returned to South Australia. In the 1860s, Angas purchased from his father the fine residence "Prospect Hall" on Torrens Road at the corner overlooking the Park Lands (not to be confused with
J. B. Graham's "Prospect House", aka "Graham's Castle" on Prospect Road,
Prospect). which served as his home while parliament was sitting. He was anxious to preserve the amenity of the area, and went to some pains to dissuade tradesmen such as the
Champion Brothers from establishing disagreeable industries nearby. He was a member of the
Royal Agricultural and Horticultural Society and its president from 1886 to 1888. From 1871 to 1875 he was a
South Australian Legislative Assembly for
Barossa. He was elected to the
South Australian Legislative Council in 1887. ==Philanthropy==
