Other England-speaking regions have followed suit, with the exception of England and Wales where it is still slightly more popular for boys.

It was also borne by the American author Mark Twain (1835-1910), real name Samuel Clemens, the author of The Adventures of Tom Sawyer and Adventures of Huckleberry Finn.

The English names Jacob and James derive from the same source, with James coming from Latin Iacomus, a later variant of the Latin New Testament form Iacobus. Unlike English, many languages do not have separate spellings for the two names.

Jacob came into general use as a Christian name after the Protestant Reformation.
