Hey Fish, your exposé of double-barrelled last names, ending with the last name your children use, reminds me of an article I read somewhere (uhhh, think it might have been in Maclean's, "Canada's news magazine!"): the young couple took each other's names, both of 'em did. Can't remember the names in question, but here's how it went:

Bryan Smith was marrying Lydia Jones, so they became the Smith-Joneses, and he was Brian Smith-Jones and she was Lydia Smith-Jones.

Think that was how they arranged it (ie, I don't think the woman's surname went first). The article was written by the wife, who said that people they met were surprised that her husband had taken her name as well, resulting in their both being hyphenated.

Let us go in peace to love and serve the board.
