Anna and Giuseppe were both married and out of the house by 1930. That's why you don't see them in the census with the rest of the family. Also, Anne and Charlie are still alive. Anne will be 92 in March. Charlie has alzheimer's. My Dad was born in 1919, and grew up with his Orlando aunts and uncles almost as brothers and sisters, due to the ages being so close. As to the English names, my Dad's parents named their children with Italian first names, and no middle names, then after Confirmation the child usually used English versions of his first name with the English confirmation name as the middle name. That's how my Dad went from Giovane to John Michael. By the way, before he died in 1982, he gave me the Italian names of all his Orlando aunts and uncles. Your grandfather was born "Onofrio". Thomas was probably his confirmation name. Please reply to my email, and we can compare notes.
