Need your help

more than 10 years ago, I saw a film, in witch the musketeers were dead (except for Porthos) and their children decide to go and save the king (or something like that). Athos or d'Artagnan had no sons, so it was the daughter of one of them who joined the three other sons.

I don't remember the title of the film, all I remember are a few scenes.

Can someone please tell me the title, and if it is possible of course, where I can find it?

It was an old film, propably made during the 30'ies, 40'ies or 50'ies.

Thankyou for your help
