I would be happy to hear your thoughts on the following matter: the etymology of Cansino. (This is all speculation on my part, so thank you for bearing with me.) "Cansino" resembles other Sephardic names such as "Almosnino" or "Sonsino". The root of the latter would be "almosn" and "sons", and the sufix "ino" would have been added to "sephardize" them. If this theory were correct, then the Hebrew root of Cansino could be K-N-S, as in knesset. I have found the name Cansino spelled as Kansino, Cansi and Kansi; one Isaac ben Samuel ha-Sefaradi ibn al-Kanzi was a halakhist, judge, and liturgical poet born either in al-Andalus or in Egypt; and a Samuel Kansi, Jewish French astronomer of the fourteenth century.
