off the top of my head I would suggest "Burkes Peerage"
Now I know nothing about that listing but they do list all the nobility.
Maybe next time we speak we should address you as HRH Vicki.[ Ha Ha.]
Hope you have a good sense of humour. No offence meant.
Next week I will get out from under the sewing machine. I've altered two
dresses and two pairs of slacks yesterday for a friend. and Have curtains to
do for her too.
