Isaac ben Abraham of Dampierre (Isaac ha Bahur, or "RIBa"), 12th/13th-century tosafist, brother of Samson ben Abraham of Sens
Rabbi Jonathan ben David ha-Kohen of Lunel (c. 1135–after 1210) was a leading French tosafist.
He was probably born in Falaise, Calvados, where his grandfather, the tosafist Samson ben Joseph, called "the Elder", lived.
