i dont know if anyone will read this.
I am Louis DiGioia III. My grandfather, Louis I, was one of 9 and had 4 brothers. His father, Cominciare DiGioia was one of 13 but the other 12 were all girls so the name would not have carried.
In 1920 NY, according to this website, my grandfather, born 1913 in Brooklyn, was one of only one of a few families with that name.
So we all might be related somehow. My son, Louis IV, is now 6 and hopefully will produce King Louie V one day. We'll find out.
