Roger was the second bishop of Lydda and Ramla from at least 1112 until 1147. Roger's origin is unknown. He succeeded his predecessor, Robert, sometime between 1103 and 1112. Whether a reference from 1108 to a bishop with the initial R refers to Robert of Roger is unknown. The historian Bernard Hamilton considers it likely that the patriarch of Jerusalem, Ghibbelin of Arles, appointed Roger, whom he describes as "a man of real ability". Lydda was a suffragan diocese of Jerusalem.
