I love old-fashioned names so I think this sibset is fantastic! I adore
Adelaide and
Matilda is also very lovely! I've never heard of someone actually considering
Jamesina but I really like it!
I was wondering, how are you pronouncing Wason? Is it wah-son or way-son? I'd never heard of that name but it has a very handsome look to it!
So you're looking for other boys names? Let me see...

Any that you like?
These could work as either first names or middle names. I tried to suggest names that went with your girls names but also some that seemed similar to Wason. I had a bit of difficulty in trying to peg what kind of boys names you like.
