seems to follow the same 1st conclusions as ML, also listed are the others found in the various Wikipedias of the various languages
but however ML identifies an exact doble coinciding generation above/!\
B. SIGNORI DI RAMA (IBELIN)
https://fmg.ac/Projects/MedLands/JERUSALEM%20NOBILITY.htm#BalianIbe...
The origin of this family is unknown but was presumably relatively modest, as contemporary chroniclers were silent on the point.
--> According to the Lignages d'Outremer[777], the first known member of the family, Balian, was the brother of Guilin Vicomte de Chartres. <--
-It has also been speculated that the name "Balian" is of Italian origin, being the French version of Barisanus, a name which is found in Pisa and Sardinia. If this is correct, Balian may have been a Pisan who came to Palestine in the entourage of Daibert Archbishop of Pisa, who was appointed Patriarch of Jerusalem[778].
-Alternatively, the derivation could be from "inhabitant of Bari" (in Calabria).
-Rüdt-Collenberg[779] favours a Norman origin from southern Italy. This is based on the likelihood that Hugues du Puiset Count of Jaffa would have chosen a fellow countryman as his constable at Jaffa, and also because the first names of individuals in charters in which Balian is listed are more Norman than Italian in origin (Jordanus, Osmond, Raoul, Humbertus, Ramundus, Radulfus).
Of all the families of Outremer, the Ibelin were unique in the extent of their dynastic connections with the royal families of Jerusalem and Cyprus and the length of time over which their political influence in these states lasted, although they were never promoted to kingship themselves.
