Recently I learned that the family name of Charles Chaplin may have Russian roots. A search on Wiktionary proved the name to be indeed of Russian origin, although the American pronunciation of the name would probably be transliterated into Cyrillic as "Чеплин" or "Чэплин". A known contemporary bearer of the name is Всеволод Чаплин.
Does the word have a meaning in its root form? What I am looking for is something along the lines of "Ковалёв" and "Кузнецов", both deriving from words for a blacksmith, or generally any other meaning attached to it beyond a bare name.
