What is the plural of 'Mr' and 'Mrs'?

[Marc]

Hi Alan, Torsten,

In Michael Swan's 'Practical English Usage' , page 524, I read that you can say and/or write for example:

The courts martial (...or the court martials)
Mohters-in-law (...or mother-in-laws)
Tell me what you think, because in Dutch we always make a plural of the first part of the noun for example:

Secretaris-Generaal (=Secretary General in English) becomes Secretarissen-Generaal and not Secretaris- Generaals

But what is the plural of Mr and Mrs? Now, you know that I am a huge fan of 'Dynasty', and Joan Collins. Starring as Alexis Colby, I once heard her say: 'There are two Mrs Colbys, now'. I think this is correct, since 'There are to Mrses Colby' sounds so strange.

Bye, and sleep well tonight, for I probably won't

Hi Marc,

I hope you had a good night despite the plural of Mr and Mrs.
Anyway, you are right — when you talk about two people with the same surname you add an «s» to the surname rather than the Mr or Mrs.
When you want to address a number of people with different surnames you simply say «Ladies and Gentlemen» or «Gentlemen».
