[10] Five of the original six mainland parishes of Charlotte County used names of major saints recognised by the Church of England: Andrew (Scotland), David (Wales), George (England), Patrick (Ireland), and Stephen.

[11] Saint David Parish is bounded:[2][12][13] Saint David joined the Cape Ann Association block in the north with the Penobscot Association block around Oak Bay and the Admiralty mast reserve between them.

In 1881 five grants in Oak Bay to the northeast of the junction of Board Road and Route 760 were transferred from Saint Croix.
