  1. From Bacchus possibly via Бахус?

  2. David D.

    You probably already know that some people think this name is a Latinization of ‘Bohuslav’ (e.g.,, Without knowing any Slavic languages myself or the history of Latinization of Slavic I have no idea how plausible this suggestion is.

    This is still fun! Thanks for continuing this series.

  3. There’s no question that it’s Western Slavic, probably Czech or Slovak (compare Bohuslav, and other Slavic names that descend from Proto-Slavic *bȏgъ).
    Wiktionary says ( ) that it’s similar in meaning to the Greek Τῑμόθεος. In other words, a rough equivalent in Modern English might by “Timmy”.

  4. Ioanna

    Is the name related to Bohemia and the Bohemians, a region and people that share so much history with Moravia and the Moravian Empire? The etymology comes from the Gallic tribe Boii, possibly meaning ‘herders’ or ‘warriors’, and the Germanic ‘haimaz’, meaning home. It’s also related to where Bavaria gets its name from: baiovarri, meaning the ‘Boii settlers’,

    As far as given names go, all I could come up with was the name Boet(h)ius, which is generally considered to derive from the Greek word ‘βοήθεια’ for ‘help’. As I also suggested in the post for Ephrod, I wonder if somehow a spelling mixup can make ‘Βοήθιος’ look like ‘Bohusius’. In addition, many Greek male names are Latinized with a “sius” ending.

    The Scottish historian Hector Boece/Boyce/Boise is known as Boecius or Boethius in Latin. This suggests that Boise, French for “wooden”, may also be related to Bohusius. The ‘Bo’ beginning also made me think of Boris, which a Serbian man told me means ‘warrior’ or ‘fighter’ (like Booi). The internet offers a more unclear picture as to the origins of Boris.

    I don’t have the know-how to make precise and accurate linguistic connections, but it’s possible that these suggested words and names are all related to each other. These name mysteries must be fun to research.
