Sir Richard Henry Bonnycastle (1791–1847) was an English officer and military engineer who served in the War of 1812 and ultimately settled in Canada. I stumbled upon copies of some of his charts and maps, became infatuated with the hand-lettered titles—and the result is the eponymous Bonnycastle.
The font has a bold weight and an italic style but is intended as an eyecatching standalone, evocative of its period in history. Bonnycastle has more than 1,100 glyphs. OpenType features include true small caps, alternate upper- and lower-case alphabets, contextual and discretionary ligatures and alternates, lining and old-style figures, cartographic ornaments, and support for Central and Eastern European languages.
