[Opinions] Re: If you had twins today..
Caspian Lucian Edward - Love this! Its very handsome and classy sounding, IMO. Caspian Edward Lucian also works very well.
Remus Maximilian Stewart - Remus and Maximilian are favourites of mine, too and it flows well. Although I don't really like Stewart (sorry), I love the fact that its honouring family.
Arabella Zoe Evelyn - Flows beautifully and all three names are gorgeous. Lovely combo!
Rowena Sophie Matilda - I'm loving Rowena ATM and Sophie's a great mn. Matilda's not really my style but I can see, it really fits with your naming style and it makes a nice combo.
