Easton's 1897 Bible Dictionary:

Accho
   sultry or sandy, a town and harbour of Phoenicia, in the tribe
   of Asher, but never acquired by them (Judg. 1:31). It was known
   to the ancient Greeks and Romans by the name of Ptolemais, from
   Ptolemy the king of Egypt, who rebuilt it about B.C. 100. Here
   Paul landed on his last journey to Jerusalem (Acts 21:7). During
   the crusades of the Middle Ages it was called Acra; and
   subsequently, on account of its being occupied by the Knights
   Hospitallers of Jerusalem, it was called St. Jean d'Acre, or
   simply Acre.
