Släkthistoria för Jouce
Jouce Vad efternamn betyder
of uncertain origin; perhaps from Middle English juce jouce (Old French jus) ‘a liquid extract obtained by boiling herbs’ although this seems an unlikely origin for a nickname even for an apothecary as suggested in Reaney and Wilson . Whatever its etymology it is not certain that the medieval name has survived. Rare post-medieval examples of Jouce may be scribal errors for Joyce while Juce is likely to be a mistaken transcription of Ince.
