While there isn't a direct English translation for the surname "Valjean," it's likely a combination of French words that have a meaning. One possibility is that it is a combination of "val" (meaning "valley" or "worth") and "jean" (meaning "John").
Therefore, Jean Valjean could be interpreted as "John of the Valley" or "John of Worth" in English. However, it's important to note that the surname "Valjean" is fictional and doesn't have a definitive meaning.
