Question: Who is the paternal grandfather of Rupen Of Montfort?
Sentence (from "Humphrey of Montfort"): When Humphrey's older brother Jean died in 1283, Humphrey was allowed to succeed to Jean's Lordship of Tyre by King Hugh III of Cyprus, who had a few years earlier confirmed the Montforts in their possessions of Tyre but reserved the right to re-take the fiefdom if Jean died without issue.
Relevant evidence: No
