Direct ancestor of Giangiorgio Trissino dal Vello d'Oro (1478-1550) through a son of Ciro. Ciro's great-grandchildren are not known at this time (Decmeber 14, 2014); however, the descendants of Teodoro have continually used the name Giangiorgio so that may be a clue that Giangiorgio Trissino dal Vello d'Oro (1577- ) is a direct ancestor. But that is all currently just assumptions since there is a 200 year gap in known information.
