Derwent Llwyd; June 7, 1861 – February 22, 1933) was an Episcopal cleric bearing the title of the Reverend who served in a number of churches across the United States and Canada.

Of English descent, Lloyd worked at or rectored churches in Indiana, Wisconsin, Illinois, Nebraska, and Washington, and was the Episcopal Dean of Nova Scotia.

Under his supervision, the Seattle St. Mark's church and its premises were renewed and improved, and the number of people in the congregation considerably increased.

He was a Halifax Explosion survivor, and during the tragedy actively participated in search and rescue missions, closely worked with the city's authorities and consoled the victims.

His second year Lloyd spent studying and working in St. George's Parish, New York, being tutored by the Reverend W. S.

[15][3][5] In 1889, after leaving St. Paul's, Lloyd became a rector in the Church of the Good Shepherd in Omaha, Nebraska, and stayed there for eight years.

[1][16] Under Lloyd's management, the church was extended and renewed, new lands were acquired, a new organ was purchased, and a rectory, appraised at $6,200 ($163,000 in 2020 dollars[note 1]) was built.

The new library couldn't be finished due to various obstacles and the lack of funds, and Lloyd played a key role in soliciting an additional $20,000 ($529,000[note 1]) from Andrew Carnegie, a Scottish-American industrialist and philanthropist.

[24] In the course of his life, Lloyd was a member of a number of fraternity organizations, including the Masons, the Knights of Pythias, the Ancient Order of United Workmen, the Elks, and the Odd Fellows.

[26] At the time of the explosion, Lloyd was reading the Morning Prayer in the chapel of All Saint's Cathedral, accompanied by his wife and two other women of his congregation.

Lloyd described his feelings at that moment in a letter, saying he thought it was "a German shell" and he felt "a sensation of utter powerlessness."

[29] He worked on search and rescue for four hours straight, and then met with the city authorities to discuss options on where to place the temporary mortuary.

After a brief stop at home to change, he headed to Camp Hill Hospital to provide comfort to victims there and listen to what they had witnessed.

[22] In his letter, published the following year in Seattle Daily Times, Lloyd expressed admiration for Halifax authorities, citizens, and American people in general for their quick efficient reactions to the catastrophe.

[30] In 1907, Lloyd refused to preside over the marriage of a 26-year-old woman and her Chinese groom, who had travelled from California to Washington to get married.
