I agree with you, Luca, but I have found that, in some towns, there is so much variation in the script on a single page, that sometimes it doesn't matter if you see an entire page or not. But, that can't be determined until we get to see the entire page of the document, and I do agree that the entire page should be uploaded to this website, as it may help us better determine the correct spelling of the surname.
I still think the surname is Lenza, despite slight variations in the capital L's in the record. Maybe someone else on this forum will perceive the surname differently. Other than that, I really don't know what other surname to suggest.
Just a suggestion. If surnames are indexed alphabetically on your microfilms, you might want to see if you can find this surname in any of the indexes, even if not for a record you need. Doing that might give you a clue to the correct spelling of the surname in your town.
