No. The sentence is in English, and the English version of that name is
Jacob.
Jacob and
Jakob are both regional variations of the original name. If the sentence was in one of a number of European languages that use the
Jakob spelling, then
Jakob would be correct; but since the sentence is in English,
Jacob is correct.
