1. How many children did St Eberhard, margrave & duke of Friuli and Giséle of Cysoing have, depending on sources this number ranges from 4-13! And an additional (single) source shows Eberhard with a second wife/mistress who fathered one additional child, not even inferred anywhere else! But we have the will of Eberhard and Gisela that identifies only seven children receiving inheritance, however, the article on Eberhard by the Treccani Institute names nine children, eight of whom inherited.

2. There was Gerold II and Erich of Friuli who both fought and died in the same year (799) against the Avars. And then later their progeny, Gerold III (Gerold II's nephew; likely father of Adalric, St. Eberhards's nephew) -- and "Baldric" of Friuli were sent again to fight the Bulgars in 826. Baldric of Friuli was “likely” Gerold's brother-in-law, Adalric's uncle and brother of St. Eberhard. Was this Baldric the same as Baldéric de Betüwe, comte de Betüwe ca 810-846 brother of Saint-Evrard de Frioul in some sources who was also marquis de Fruili 819-828 and who in 828 was “removed from office” as marquis by Eberhard for his “failure to have mounted an effective defense against the Bulgars during their invasion of 827”? (marquis at 9, fired at 18?).
