Bucking the trend, I love two middles. I am British but I can’t say it’s a big thing in my family. I’d say 90% of my family have one middle and some have none but a few relatives do have two and as far as I know it doesn’t affect their lives in a negative way at all! It’s something to consider, but I think people overstate it. Unless you use 3 really long names, and have a really long last name, or you use more than two middles, I don’t think it’s a big deal. I went to school with a girls who had 4 middles! Now that was too much lol.
Maybe it’s different in the US but in [name]Britain[/name] most forms I’ve seen that ask me to fill out my name, either has a freehand section saying first name(s) where you can write them all, or has a first name section and then a part saying middle initial(s).
Having said that I also like your middle name combos but the first names aren’t my style. I don’t like that the word Temper is in [name]Temperance[/name] and I dislike names ending in [name]Son[/name] for girls since they mean “son of”. That’s just me though, other than that they flow well
