As a foreigner, I noticed that english native speakers use both the series round 
/ square / curly / angle brackets, and individual terms parens (no 'd' ;-) / 
brackets / braces / chevrons. No major issue, except for 'brackets' which can be 
either a collective term or specific to [].

Apparently, according to wiktionary, it may come from an old germanic root 
through Gaulish:
https://en.wiktionary.org/wiki/bracket#Etymology
<< Etymology

 From earlier bragget, probably from Middle French braguette, from Old French 
braguette (“the opening in the fore part of a pair of breeches”), from Old 
Provençal braga, from Latin brāca (“pants”), from Transalpine Gaulish *brāca 
(“pants”), perhaps from or related to similar forms in Germanic: compare Old 
English braccas (“pants”), Old English brōc (“breeches”), from 
Proto-Indo-European *bʰrāg-, from *bʰreg- (“to break, crack, split, divide”).
