Re: Juniors and "Numbers"
I don't like it, honestley. It seems incredibly egotistical and uncreative, and I think every child deserves their own name and the chance to be their own person. I would fight my husband tooth and nail on this- particularly if he wanted a junior, or even a III. If it was say a 4th or 5th, I'd be more open to it, because I'm a big one for traditions, but even then I don't think I'd be happy. If he really felt strongly about it, I'd be willing to consider either or both names as middle names. Wether I liked the names or not wopuld have to be factored in, ofcourse.
That being said, I definitley don't feel as strongly about other people doing it- I don't like it, but each to their own, especially if they are carrying on a tradition, as in your case, and not simply just trying to recreate the son in the fathers image. I just really don't like it for my kids.
My aunty broke tradition when naming my cousin. They had boy/girl twins 6th years ago. My uncle, who is a Jr. wanted his son to be Frederick Vaughn the 3rd. My aunty said no way, not happening, so he was named James Frederick. His twin sister is Charlotte Sophie.
