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.

One of the sequels based in Italy features Cesare Borgia as one of the "bosses" that have to be slaughtered by the protagonist. Borgia was a statesman IRL in Italy in the 15th century

@Nomad7 in all the sequels, pretty much every character is well known IRL.

But in AC1, characters were vaguely named (different from their IRL name) making it difficult to track their real life counterparts
