I came across two real-life British sibsets just now. The two sibsets are cousins---their fathers are brothers.
Arthur, Delilah, and Henry.
Otto and Pearl.
I know that Arthur is much more popular in the UK than in the US. But as I'm American, it caught my eye, as did Delilah.
Otto and Pearl really caught my eye, too. I can't find anything redeeming in Otto, though I do find Pearl retro-charming. I like Delilah, but I think it has a "vamp" vibe due to the Biblical story that I think would render it unusable to me personally.
What do you think?
