The city directories show that Thomas Ball worked as a plumber for Cunningham Hardware in New Westminster, starting in 1909 until 1929-1930.
Cunningham Hardware was a fixture in downtown New Westminster on Columbia Street. It was owned by Jim Cunningham (1834-1925), a local hardware merchant and real estate investor, who was helped to rebuild New Westminster after the 1898 fire which ravaged the Royal City's downtown core. Cunningham first came to British Columbia to mine the goldfields in 1860, and settled in New Westminster. He used his assets to invest in real estate in the growing city; and, in 1904, he was recorded as the 'chief taxpayer of the city'. He was prominent in local affairs, elected Mayor of New Westminster in
1873, and Member of Parliament in 1874-78. (Source:Cunningham Block and New Westminster News Leader).
