- a surname/nickname (Roberti litelboie, Willelmi Godeboye, Alanus Boye, ...)


b) Borrowing from French

- boie: aphaeresis (a shortened form) of the Anglo-Norman word emboié/embuié/enbué (ADJ - 'fettered' or N - 'a person in chains')

- boiasse: a French word for a female servant; -asse as a female suffix, analogically male servant without the suffix

Low German boi

Frisian boai

all of these forms could originate from a nursery form of the word 'brother' (cf. German Bub(e))
