I am doing some genealogy research on my family, but am having a very difficult time with the Priora line because I cannot find any information on it. My Grandmother was Joyce Priora. She was born in 1925 to a Minnie Virginia Priora in Queensland. My grandmother was given up for adoption and her name was changed to Margaret McWilliams. I am trying to learn more about her real family solely out of interest. Does any one know, is Priora a common last name? Does anyone have this name in their tree?
