I'd be surprised to meet a modern
Reginald; also a
Giles, but it's not so bad, probably because it resembles
Miles. I find
Maud deplorable, though I once taught a delightful one.
Loretta and
Annora seem almost aggressively 20th-21st century, and Flandrina absolutely amazes me. Can it be geographical/political -
Lady From Flanders?
I'd use or at least consider using
William,
John and
Margaret.
