1: Valerius Proietto di Venezia - Resub Name
Submitter desires a masculine name.
The original name submission, Valeas Proietto di Venezia, was returned by Laurel, July 2017 "due to lack of evidence for Valeas as a name element. The documents cited in the Letter of Intent show the name as Valens, not Valeas. All of the instances of valeas found by commenters were for a Latin verb form, not a name (or even a noun).
"Heralds at the Pelican decision meeting were able to document both Valens and Valerius as given names compatible with the remainder of the name. However, the submitter allows no changes. Therefore, the name must be returned. His device is registered under the holding name Dennis of Tir Ysgithr."
Valerius is a male Roman nomen found in "A Simple Guide to Imperial Roman Names," Ursula Georges (http://yarntheory.net/ursulageorges/names/roman.html). I haven't found it as an Italian name, although the folks at the Pelican decision meeting seemed to have found it compatible with the rest of the name.
Maridonna Benvenuti provided additional Proietto documentation as a saint's name. In a 1612 book, "Compendio delle vite di tutti i santi." by Lodovico Zacconi, pg. s.n. Proietto, "PROIETTO Vescovo Averniense & martire, per le mani de suoi cittadini pervenne alla palma & corona del martirio con S. Marino huomo di Dio, l'anno di salute 670... la sua festa viene alla 25 di Gennaio." A translation, PROIETTO Bishop, man of Auvergne & martyr, by the hands of citizens received the palm [leaf] and crown of martyrdom with S. Marino man of God, the year of recommendation 670 ... his feastday comes on 25 of January.
The search returns another Proietto (not a bishop) whose feastday is January 24th, Tavolo Seconda, month of Gennaio, third page of the list. https://books.google.com/books?id=IBxSAAAAcAAJ&pg=RA2-PA9&dq=Proietto&hl=en&sa=X&ved=0ahUKEwiz3quwo9 HUAhWF8oMKHTSNCykQ6AEILTAB#v=onepage&q=Proietto&f=false.
According to the Catholic Online.org this saint is still venerated on January 25 under spelling of St. Praejectus. He was born in Auvergne, France http://www.catholic.org/saints/saint.php?saint_id=5458
da Venezia (rather than de) is a locative byname based on the city of Venezia, found in "Florentine Renaissance Resources: Online Tratte of Office Holders 1282-1532," David Herlihy, R. Burr Litchfield, and Anthony Molho (http://www.stg.brown.edu/projects/tratte/doc/ORIGIN.html).
