Abraham ben Joseph of Orleans

Abraham ben Joseph of Orleans (רבי אברהם בן יוסף c. 1140) was an early 12th-century French Tosafist and the son of Joseph Bekhor Shor and the brother of Saadia Bekhor Shor. Some have suggested that he is identical with Abraham ben Rabbi Joce (the Chief Rabbi of London in 1186). Many of his interpretations of the Talmud are quoted several times in the Tosafot.
