The date and name of the spouse for the first marriage looks correct.
I think the reason there is not a second "i" in Luigia is that the name is Luisa and not Luigia. Look at the word sposi right above her name. The second s in that word looks like the letter in her name. So I don't think it's a g. I think it's an s in her name.
The date could be October 21, 1915 (the last two numbers in the year, I am not sure about)
