[9] 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.

The western line of the parish was the same; the eastern line ran along the eastern side of the Letang River, Letang Harbour, putting all the islands in them in Saint George; the southern boundary extended to include all islands within 2 miles (3.2 km) of the coast, including islands that are now part of West Isles Parish.

The eastern line diverted around a grant on the Letang River that's mostly in Pennfield Parish along Route 785.

[13] In 1850 the eastern line was extended south to the Letang River, taking part of Pennfield Parish; the Letang boundary was reworded, implying that the western shore was the new boundary of Saint George.

Bonny River-Second Falls took in an area west of the Magaguadavic River from the parish line south almost to the Old St. Andrews Road and grants east of the river from the Red Rock Road to The Canal.
