However, given the long period between the beginning of Matthew's reign in the first years of the 13th century and the attested date of Richard's death, it is possible that another character is to be intercalated between Matthew and Richard, perhaps the "count Theodore" referred to in a document from 1264 (possibly Matthew's son and Richard's father).
Con todo, dado o longo período entre o comezo do reinado de Mateo nos primeiros anos do século XIII e a data testemuñada da morte de Ricardo, é probábel que outro personaxe fose posto entre Mateo e Ricardo, quizais o «conde Teodoro» referido nun documento de 1264 (posibelmente o fillo de Mateo e o pai de Ricardo).
