No problem. After comparing /u/xanaboobs's transcription to the photos, it was a lot easier to figure out what it actually said. Some parts are still not clear, but you get the gist. I tried to see if I could find any information about P.R. Falkner and this genealogy website came up with a similarly named baby born in Bilbao in 1844, so perhaps you're related to this baby. And if it's the same P.R. Falkner, this could be your family tree.
Sure. Amazon has them here https://www.amazon.com/Spencerian-Handwriting-Collection-Practical-Workbooks/dp/1612435289 Or here as one single volume https://www.amazon.com/Spencerian-Handwriting-Collection-Practical-Workbooks/dp/1612435289
I’m glad I’m not the only one who’s messed around with writing kanji with a nib. Personally I ended up writing with a made up style that was better suited for the pen. I would recommend finding a brush-pen at a craft store if you want to practice Japanese calligraphy, but don’t want to go full on brushes and ink. I personally own a few different sizes of this brand.
You don't even need to get an old one. There are calligraphy sets in most art stores (you'll usually find new Shaeffer sets, which I've heard mixed things about), and Pilot makes a cheap (for a fountain pen) italic pen which can be had for around $10. Most of the people who have come to me asking for a starter pen, after seeing my writing, were happy with a Pilot Plumix
When I took my architectural drafting course, we used this template to make lines in light pencil (which would be erased later):
