In Scotland this Hebrew name became popular in the 17th century because of it’s association with the Gaelic ‘beath’ meaning “life”.
The name Beth is derived from the names of MacBeth and Bethune, or Beaton.The Beth family history stretches back tot the clans of the Dalriadan Kingdom on the Hebrides Island and mountainous western coast of Scotland.The MacBeth and Bethune families were hereditary physicians to the Chiefs of MacDonald practicing medicine on the Isles during the Middle Ages.Later, the name transformed into Beaton when the familie started migrating into England as well.
