abbreviations - usage of "Mrs" for male

As far as I know, abbreviation "Mrs" is applicable only to womens.
Though, I try to translate article from old British paper and I meet this sentence about marriages:

On the 2nd March, at the British Embassy, Paris, LIEUTENANT GENERAL NAPIER CAMPBELL to CAROLINE MARGARET DUFF (Mrs. HENRY PRICHARD), daughter of the late Deputy Surgeon-General Charles Murray Duff

Can anyone tell me what means this "Mrs" in this context? I understand that Henry is only male first name.
I thought that maybe this is just person who gives marriage, but this discrepancy between "Mrs" and this name confuses me.
