This is purely for entertainment. I would have put this in the Writers’ Forum, but it doesn’t get nearly as much traffic/response.

The oldest child in a family is named [name]Opal[/name] [name]Araminta[/name] Owenby. She has three younger siblings - two boys, one girl - who also have “O” first names and elaborate, unusual middle names. They come from a quirky British family. What would you name the three younger siblings?
