Matthew Fielding Locke
After the war, Locke returned to Mississippi, and in 1849 married Elizabeth A. Biue. Shortly thereafter they moved to Upshur County, Texas. He established a plantation about 13 miles (21 km) northeast of present-day Gilmer and founded the nearby town of LaFayette (which he named after his son, LaFayette C. Locke, who was born in 1850). Locke began the first of two terms as a state representative in 1855 in the Sixth Texas Legislature. In the Seventh Legislature, Locke was elected Speaker of the House "pro tempore" on 26 December 1857 when Speaker William S. Taylor took ill. When Taylor resigned on 18 January 1858, Locke was elected Speaker over Reps. Isaac N. Dennis and John Henry Brown, 39 votes to 14 and 13, respectively.
Keith Locke
Locke was born and grew up in Christchurch, to Jack and Elsie Locke, prominent lifelong political activists for a wide variety of causes. Their four children were brought up in this environment and followed their parents into a life of activism, (as well as Keith, his sister Maire Leadbeater is a well-known activist and former city councillor for Auckland City Council). His father Jack was under surveillance during the 1951 New Zealand waterfront dispute.
Former Prime Minister Robert Muldoon is said to have described the Lockes as the most "notorious Communist family in New Zealand". The Lockes lived in the Avon Loop area of the Christchurch Central City and were very active in the community notably organising Avon River clean-ups and native tree planting and arguing against development of the area, and in favour of retaining the character of the area.
