I completely agree with LEPORE as I'd used the same reference for the letter "L".
I guess the proof of the pudding would be s marriage record but it could still be a needle in an incomplete haystack, even if I knew a date or place. I'm going to see if I can pull together information about Vincenzo's and Matilde's children - the year/place of birth of their eldest child may guide me to their marriage details.
Meantime, I've managed to adjust the image so as to make the handwriting stand out more. I've passed it to my Aunt but she's currently snowed under with work (and she's supposed to be retired!!)
I've also popped a related post on here in the hope someone can decipher.
Thanks to your kind help, we have one document so fingers-crossed!!
