Can’t name son after the father....

So I’m 12w2d and I already have 3 girls, so I’m hoping for my boy this time around. Anyway if I ever had a son I wanted him to be named after his father (Nicholas Joseph) but due to the fact he already has a son named after him from a previous relationship (he also has a daughter) so with this child this will be his 6th, the other 2 are older now 18,16 and they are a big part of our lives, I’m saying that because sometimes things are different in other relationships! I have been with him for 16 years since right after his son was born. The kids mother and I are really good friends and never had problems with each other, I’ve loved those kids like they are mine from the start and still do just as much as I love my own which are still kinda young 11,8,7...

So I guess I can call this a rant lol, just wanted to get it out that I’ll never be able to name a son after the father, but if any of you ladies have any suggestions that’s greatly appreciated oh and I do not want the name Joseph Nicholas, since I already have a Joseph in my family also but I just can’t think of anything that is remotely close or that sounds good, so I’ll probably just have to go with a name we find and like ughhhhh 😞 I’ve always wanted a Jr.

Rant over!!!!!
