Just a quick note to let you know that I will have to get back with you.
I evidently did quite a bit of research on the Quartararo family when I "inherited" their memorials in the Italian Cemetery. However, the notes that I kept aren't very good (or just don't make sense to me at the moment).
Interestingly, though, I have a note about your Salvatore to myself that says: could he be the son of Carlo (memorial 62390746) in the same cemetery and could Carlo be the brother of Salvatore (memorial 44413642) and Vincent (memorial 107708254)?
So give me a couple of days to refresh my memory and I'll get back with you. Would be great to solve the mystery? Thanks for getting in touch -
