Giovanni Gioia was my Great Grandfather. He was born in Italy in 1860. I don't know what part. Somewhere along the line he changed his last name to Joy, and his first name to John. He was possibly married to a Serefina Senese in the late 1880's and had a daughter with her named Genevieve Joy, born 1890. He later married Carmela Marinaro and had two sons Guisseppi and James. He died in 1902 and is buried in St John's Cemetery in Queens NY, under the name John Joy. Anybody know of Gioias changed to Joy?
