I ForgetTFW you should probably be doing More Important Things, but last night you stumbled on the 1846 marriage processetti of your wife's Gx3Gparents and it has handwritten copies of documents like the 1813 death record of her Gx5GF, who was 82 at the time, with his parents' names, so Obviously you have to Stop Everything and Immediately Copy Everything.
Also. For my sighted friends, if you have any appreciation for beautiful handwriting, check this out. Hand-copied in 1846 from an 1813 original. Italian, but the handwriting is beautiful even if you don't know the language.
