Jackson began as an English surname meaning "son of Jack". Jack in turn is a pet form of John, from the Hebrew Yohanan, "Yahweh is gracious". The chain of derivations keeps Jackson's Christian root intact even at three removes.

No Jackson in the Bible. Its ancestor name John is borne by John the Baptist and by John the apostle, "the disciple whom Jesus loved" (see the Bible page on John).
A blessing for Jackson
Jackson, may God be gracious to you, the way the older name behind your name promises. May grace show up on the days you know you did not earn it.
