You weren't kidding...

I looked everywhere and scoured the Dark Web and managed to only find this after great struggle:

There exist several versions of this figure's name in gospel manuscripts, most commonly simply Biblical Greek: Bαραββᾶς, romanized: Barabbās without a first name. However the variations (Biblical Greek: Ἰησοῦς Bαῤῥαββᾶν, romanized: Iēsoûs Bar-rhabbân, Biblical Greek: Ἰησοῦς Bαραββᾶς, romanized: Iēsoûs Barabbâs, Biblical Greek: Ἰησοῦς Bαῤῥαββᾶς, romanized: Iēsoûs Bar-rhabbâs) found in different manuscripts of the Matthew 27:16–17 give this figure the first name "Jesus", making his full name "Jesus Barabbas" or "Jesus Bar-rhabban", and giving him the same first, given name as Jesus.[b] The Codex Koridethi seems to emphasise Bar-rhabban as composed of two elements in line with a patronymic Aramaic name.[17][18] These versions, featuring the first name "Jesus" are considered original by a number of modern scholars.[19][20] Origen seems to refer to this passage of Matthew in claiming that it must be a corruption, as no sinful man ever bore the name "Jesus" and argues for its exclusion from the text.[21] He however does not account for the high priest Biblical Greek: Ἰάσων, romanized: Iásōn from 2 Maccabees 4:13, whose name seems to transliterate the same Aramaic name into Greek, as well as other bearers of the name Jesus mentioned by Josephus.[17] It is possible that scribes when copying the passage, driven by a reasoning similar to that of Origen, removed this first name "Jesus" from the text to avoid dishonor to the name of the Jesus whom they considered the Messiah.[22]

Etymology

Of the two larger categories in which transmitted versions of this name fall Biblical Greek: Bαῤῥαββᾶν, romanized: Bar-rhabbân, seems to represent Jewish Palestinian Aramaic: בּר רַבָּן, romanized: Bar Rabbān, lit. 'Son of our Rabbi/Master', while Biblical Greek: Bαραββᾶς, romanized: Barabbâs appears to derive ultimately from Jewish Palestinian Aramaic: בּר אַבָּא , romanized: Bar ʾAbbā lit. 'Son of ʾAbbā/[the] father', a patronymic Aramaic name.[17] However, ʾAbbā has been found as a personal name in a 1st-century burial at Giv'at ha-Mivtar. Additionally it appears fairly often as a personal name in the Gemara section of the Talmud, a Jewish text dating from AD 200–400.[23]
