Easton's 1897 Bible Dictionary:

Ono
   a town of Benjamin, in the "plain of Ono" (1 Chr. 8:12; Ezra
   2:33); now Kefr 'Ana, 5 miles north of Lydda, and about 30 miles
   north-west of Jerusalem. Not succeeding in their attempts to
   deter Nehemiah from rebuilding the walls of Jerusalem, Sanballat
   and Tobiah resorted to strategem, and pretending to wish a
   conference with him, they invited him to meet them at Ono. Four
   times they made the request, and every time Nehemiah refused to
   come. Their object was to take him prisoner.


Hitchcock's Bible Names Dictionary (late 1800's):
