I saw your request regarding the Bowman Haigh family
I was in the South Australian Library recently and I did some research on the family, but I found very, very little.
What I did find was:-
Thomas Richard aged 58 years, widower, son of John Bowman married 4th October 1893 to Elizabeth Haigh aged 24 years, single, daughter of John Love at St. Michael Church, Mitcham District Adelaide reference book 177 page 31 symbol 'S' denoting - The Registrar has included supplementary information on this marriage record.
1. Thomas Richard Bowman 75 years of Adelaide died 17th February 1911 at Adelaide, District Adelaide place of death not recorded, reference book 355 page 117 symbol 'S'
2. Elizabeth Haigh Love, daughter of John Love died 1939 in Adelaide.
I did not have time to look up births for Thomss Richard Bowman and Elizabeth Haigh.
