Do you know where your great grand father Giovanni was married in New Brunswick? The name of his parents should be on this certificate. My great grand father Severino DaPrato came to Canada in 1856 and from the parents name we were able to trace his family. After three consecutive yearly holidays and research in Italy I have traced my ancestors to 1655 at the church in Loppia. I am from Toronto and might be able to help you in your research in New Brunswick. I also have a lot of info on Ghiloni families in Loppia. Awaiting your reply, Jacqueline
