Trinity Church owes its foundation to Henry Trigg, a carpenter, businessman and Congregationalist from Gloucester, England. Trigg arrived in the Swan River Colony aboard the ‘Lotus’ in October 1829. His personal wealth allowed him to take up a land grant of 1,208 hectares, encompassing what is now known as the suburb of Churchlands. Trigg initially attended the first Anglican Church, where he was a choirmaster. He later joined the Wesleyans, but from 1843 he held prayer meetings in the Congregational tradition in his own home on Bazaar Terrace. Two people were present at the first meeting Trigg commented “Himself and the Lord”. In 1845 a few friends met to discuss the building of a chapel. Land was leased for 18 years in William Street and in 1846, a chapel was constructed, where for six years, Trigg conducted all the services until, 1852, when the London Missionary Society sent out the Reverend James Leonard to be the first ordained Congregational minister.
