Some Help With Reading Pencil Notes

hi all,

This isn't really a postcard as such but I know there are some talented people on this site when it comes to deciphering the written word.

Can any one help with the pencil notations on the bottom of this?
all I can make out is Joseph.

thanks.

Joseph J du ...
... age de 86 ans
Gardien du ... Luc...

I presume that the reference to Louis XVIII should read Louis XVI. Was Joseph the person referred to as the last of Louis XVI's Swiss Guard? The dates don't quite add up. If he was the person who died in 1864 in Lucerne, he would have been born in 1878, and thus very young to have been in Louis's guard, given that the king was executed in 1793, and that the massacre of the Swiss Guard occurred in 1792. But not impossible. Or he may have joined the Guard later.

thanks Geoff, yes there are errors, its actually an early tinted photograph of the man himself in his military dress, there is also further information from a family member written in the 1950's which adds to it and mentions the errors in dates etc and explains a bit further, I was thinking maybe Gardien du Monument?

Good shot - presumably this one -

Thanks for the link, here is the note found alongside,

Could you post a photo of the man in the card.? That means he belonged
to the Swiss Guards.That may interest the archives of the Swiss Guards.

You might contact the guards Swiss for some details by sending the
information you have.I'm sure they will be helpfull.
