Below is what I have found so far:
- On my grandfather's 1879 birth certificate from Alessandria della Rocca, his mother's name is listed as Antonina Corteiosi.
- When my grandfather was married in that same city in 1901, his mother's name was recorded as Antonina La Corte.
- Two of my grandfather's sisters were also married in Alessandria della Rocca in 1901. On one marriage license, my great-grandmother's name is Antonina La Corte. On the other, it is Antonina La Corteiosi.
- I have found other people in the area of Alessandria della Rocca during this time who are most likely related, but not proven yet, who have even more variations of this surname. I have seen La Corte Iosi, and even La Corte Tosi.
Sincerely,
Johnathan
