# Derby Parish, New Brunswick

## Origin of name

The parish was named in honour of the Earl of Derby, Prime Minister of the United Kingdom at the time of its erection. William F. Ganong notes that local legend states the parish took its name from horse races held in the area.

Derby was erected in 1859 from all of Nelson Parish north of the Southwest Miramichi River plus Beaubears Island.

### Evolution of boundaries

The original northern boundary of Derby was a straight line running south 68º west This put parts of modern Southesk in Derby and parts of Derby in Southesk.
In 1920 the boundary with Southesk Parish was changed to run along lot lines; these lines were sometimes grant lines and sometimes property lines. Clarifications to the boundary of Southesk in 1953 and 1954 affected Derby, producing the modern boundary.
