plural of Jacob, a masculine given name meaning 'supplanter' or 'holder of the heel'
from Hebrew Ya'aqov, from 'aqav 'heel' or 'to follow closely'
Jacob literally means 'heel-grabber' because in the Bible, Jacob was born holding his twin brother's heel! The name has given us 'Jacobin' (French revolutionaries) and 'Jacobite' (Scottish rebels).
