I have been working on my potential Trissino noble ancestors from Vicenza, Italy (still can't find or officially deny a connection to them. Anyway, it appears that they have had 7 or 8 main lines since the 11th century. The lines (created through the lineage of the sons of Olderico) have been as follows: Castelmaggiore (extinct in the XIII century with Corrado's four sons), Della Pietra (extinct with the children of Giacomo di Ammirato (James the Admired) in the XV century); Paninsacco (extinct with Francesco Trissino Paninsacco's death in 1883).
The fourth original line of the Trissino family came from Olderico's fourth son, Miglioranza, however, this one has been split into four, possibly five main branches:
-Trissino Riale: extinguished with the death of Ottavio Trissino Riale in 1779).
-Trissino Baston: extinct with the death of Alexander Trissino Baston in 1451)
-Trissino di Sandrigo: extinct with the marriage of Irene Trissino di Sandrigo to Gaetano Trissino dal Vello d'Oro in 1712).
-Trissino dal Vello d'Oro: Giangiorgio Trissino (1478-1550) gained permission for the distinction from Maximilian I of Habsburg in 1515 and was reconfirmed a knight of the Golden Fleece in 1532 by Charles V.
-Possible line of Pontefuro: if real started by Teodoro Trissino, the great grandson of Giangiorgio Trissino dal Vello d'Oro (1478-1550).
While this seems simple enough to follow (knowing the line), this was from a Wikipedia article which I attempted to fact check with several articles and found, as told in the Wikipedia article, the lines that aren't dal Vello d'Oro are found to never use the predicate title during most of their lives making it hard to distinguish. Is there anyway, besides looking through their genealogies with a fine tooth comb, that I can find distinguishes between the family lines?
This is the wikipedia article I have been using (I Google Translate to English):
Making things even harder to determine a connection is that my family has used the following spelling back at least until the 18th century: Trizzino.
Any clues on how to simplify my search?
