HI Alex
I think that what happened way back in the day is that there were a number of folks that were functionally illiterate and had to rely on the spelling of the name through memory and hearing it spoken. This would explain the subtle differences that we are seeing here. My husband's mother was Elisabetta Calla, she had one sister as far as I know, Rosa. Elisabetta married Domenico Ieraci in Calabria. My husband Giuseppe was born in Marino di Casselvelino in 1949. Rosa married shortly before the First World War, he died after only three months, Rosa was pregnant with her one and only child, Raphaelina. Raphaelina married Francesco Albanese and they immigrated to British Columbia, Canada.
My husband immigrated to BC, Canada in 1967. As fate would have it, my distant ancestor, King Rene D'Anjou (De Guise) of France was given the title "King of Sicily" through the passing of a relative. He was commonly known as "Good King Rene" and was a close friend of Cosimo De Medici and inspired Cosimo to build Europe's first Library. The Renaissance is actually named after this relative of mine "Rene's Essence" as he apparently was a great supporter of the arts and was quite the writer himself. He rode with Jeanne D'Arc for two years and was connected with the building of the Notre Dames Des Lourdes as well as the Chateau in the De Guise family line. Shakespeare wrote about Good King Rene in one of his plays.
The funny thing is for years and years I have had to endure the bragging of my husband concerning the great conquests of the Romans. Now by poetic justice I can lay claim to some pretty substantial bragging rights of my own. LOL
