I found something but nobody cares lol
So I played this game called Assassin's Creed (2007) a few months ago and in it, the protagonist has to assassinate nine targets:-
1) Tamir
2) Garnier de Nablus
3) Talal
4) Abu'l Nuqoud
5) William de Montferrat
6) Majd Addin
7) Jubair al Hakim
8) Sibrand
9) Robert de Sable
Now everybody knows that (2), (5), (8) and (9) are real characters from The Third Crusade.
And everybody thought that the others were fictional characters.
Later it was pointed out that Majd Addin could refer to
https://en.wikipedia.org/wiki/Majd_ad-D%C4%ABn_Ibn_Athir
And Jubair al Hakim could refer to
https://en.wikipedia.org/wiki/Ibn_Jubayr
And the rest were believed to be fictional characters, still.
Today, after scanning and skimming through Wikipedia pages I concluded that Abu'l Nuqoud must refer to the Damascus merchant Abu al-Faḍl Jaʻfar ibn ʻAli al-Dimashqi
https://en.wikipedia.org/wiki/Abu_al-Fa%E1%B8%8Dl_Ja%CA%BBfar_ibn_%CA%BBAli_al-Dimashqi
This made me think that maybe the remaining two characters Tamir and Talal are not fictional either.
Edit: I think I have found another one. Tamir was known to be a military supplier of Saladin. Sounds like this guy.
