Light is a surname.
Coming from Middle English, there are several possible meanings. In Middle English, lyght means a happy, cheerful person. The Old English leoht could be a person who is ‘bright’ or ‘cheerful’.
The two forms of light - leoht and lioht had distinct meanings, but became mixed over time. The Middle English word lite, coming from Old English l¯t ‘little’, also became lyght.[1]
