Gwen was right. Any name in there would be helpful. Though the fact that her dad was a Muggle just complicated things. She wouldn't find him by looking the name up in any book or yearbook in the library. What did Muggles use to track people down, anyway? 'Did you find any other names in here? Like your parents'? They were very good friends at the time, so it made sense that Ava should mention them in her diary.

Ul? 'You're thinking something like Ulric?' Ari chuckled. 'Don't forget he's a Muggle. They don't tend to have such original names like in the Wizarding world.' As far as Ariadne was concerned, they could rule out that possibility. The Gryffindor nodded when Gwen excluded other two cases. They were definitely on to something now!

Llo. And the fourth letter could be a G, a P or a Y, whereas the last could be D, M, V. Ari focused on all the possible combinations for a while, but she eventually deciphered it. 'Any chance it could be Lloyd?' she asked the Ravenclaw.

Just as she was starting to feel proud of her achievement, Gwendolyn had finished de-coding the whole last name. In the same time that she had figured out two letters. Nothing to see here, then. 'Gallagher. Lloyd Gallagher.' the fifth year repeated. This could actually be it! Now only if she had access to a Muggle library. Or better yet, the thing they called ...InterNets? 'D'you think a visit to the Muggle Studies Professor is in order?' Or was there another way forward?
