Re: Dorothy and Susanna - Do you like them?
I like all four names, though I much prefer Susannah with an -h. I would use Iris or Alice as fns and Dorothy as a mn. Susannah I could see as either fn or mn.
Iris Dorothy
Alice Dorothy Iris, why not? Or just Alice Dorothy.
Dorothy Alice
Susannah Iris
In an idle moment, I once invented Susianne! Goes well with Dorothy.
