Colonel Henry Thompson Brock was born in Oakville, Ontario  14 May 1859, son of William Rees Brock (Conservative Member of Parliament for Toronto Centre from 1900-1904) and Margaret Anna Diamond.

In 1877 he enlisted with the University College’s “K” Company of The Queen’s Own Rifles of Canada and 5 years later was commissioned.  He was one of several junior officers to participate in the North West Field Force before resigning in 1891. He rejoined with the 10th Royal Grenadiers (now the Royal Regiment of Canada) where he would eventually become commanding officer.

On 16 June 1891 he married Anna Maude Cawthra at St James Cathedral, Toronto, and they had a daughter Anna Mildred Cawthra Brock.

Brock studied law and by 1891, with fellow QOR officer R.S. Cassels and his brother, would form Cassels, Cassels & Brock Law firm.

He died at age 74 on 26 August 1933 in Toronto and was buried in St James Cemetery.
