Tancred continued to star in club cricket, gaining a reputation as the best batsman in South Africa, with a strong defence, as well as an outstanding point fielder.
Married in 1893 to Adeline Wainwright, who bore him three daughters, Tancred's increasing work commitments forced his withdrawal from the 1894 South African tour of England.
Tancred played his final first class match in February 1899 in the 1898–99 South African cricket season, representing Transvaal against Lord Hawke's touring English side but was again unavailable for the Test series due to business concerns.
During the Second Boer War, Tancred worked for British intelligence and then as Legal Adviser to the Military Governor in Bloemfontein, necessitating his absence from the 1901 South African tour of England, which it had been thought he would captain.
Following the end of the war, Tancred moved to Salisbury to open a law firm in partnership with his fellow St Aidan's alumni (and future Premier of Southern Rhodesia) Sir Charles Coghlan.
