New name for this sibset.

There is a family of a Canadian father and a British-Finnish mother with four daughters. The 2nd oldest daughter is named Mery, Finnish for [name]Mary[/name], the 3rd is named [name]Diana[/name], and the last is named [name]Tina[/name]. What would you name the oldest daughter? I need classic and popular British names, Irish is also acceptable. [name]Just[/name] names that scream Anglo.

PS. What do you think of [name]Aya[/name]?
