I looked this up a couple years ago because I was curious, Found a pretty good website for this kind of thing. http://www.4crests.com
Some stuff from the website --> This surname is universal, originally from the popular medieval given name of biblical origin. The name was originally an Aramaic name meaning 'a twin' borne by one of the disciples of Christ, best known for his scepticism about Christ's resurrection (John 20:24-9). This disciple is stated by Eusebius, on no scriptural authority, to have borne the given name Judah. Before the Norman Conquest of 1066 the name is found only as the name of a priest or a man of the cloth. After this time it became one of the most popular christian names.
But this is only my father's side of the family. Apparently, six generations back, my mother's family came over from Ireland on a travelling gypsy circus.
