The three people named Bonomi in the Cloz Parish Records married people from Cloz. All three were from the village of Vasio which is also in the Val di Non. The parish records of Vasio(1860-1923) have been micofilmed. For a very small fee, you can get a copy of the microfilm on short-term loan from any Family History Center of the Church of Jesus Christ of Latter-Day Saints (La Iglesia de Jesucristo de los santos de los ultimos dias). The equipment needed to read the microfilm is available for no charge at the Family History Center. This is not to say that all Bonomis were from Vasio, but it would be a place to start looking.
The three Bonomis mentioned in Cloz records were: Maria Bonomi born about 1800 who married Cristoforo Larcher, Giovani Bonomi b. abt 1778 who married Fracesca Michele; and Bonofacio Bonomi b. abt 1808 who married Maria Felecita Rauzi.
