I'm new to this, so please forgive me. Any possibility that an americanized nickname for Rosario could be Charles/Charlie? Long story, but I'm finding info on my great grandparents from Napoli that lists a Rosario born in 1908 in Wisconsin (2 years old) and then 10 years later it lists a "Charlie" at 12 years old, same parents, same street address, etc. Any help would be greatly appreciated! Thanks!
