Hi Neil,
It's good to hear from distant family. Your grandmother Maria is my g grandmothers sister. Her name was Margaret Loungo. She was married to my g grandfather, Antonio Acocella.
I have found info on your grandfather goinig back to the 1910 census. When you search, use the name Choavaroli. They are living in Newark N.J.
I have also been in contact with your cousin Karen D.
Please email me directly if you wish.
Joe Acocella
