I am a half-blood witch. My name is double barrelled “Snape-Riddle”. What is peculiar about this is that both of these names belong to the Muggle side of me. Perhaps you would have thought that I would be “Snape-Gaunt” or “Prince-Riddle” thereby taking one of the Muggle names and one of the Riddle names but I was given two muggle names. My full name being Sarah Louisa Snape-Riddle. The Sarah is because my Grandfather Snape apparently insisted on there being an S in my name. The name I use and am registered as is Louisa Snape. I always thought that my parents were unmarried but I found out a couple of weeks ago that they were married. I was official. My father had a house ready for us all to move in to but, times being a little different nothing worked out like that.
