Name Help!!

I’m 28 weeks pregnant and due on the 2 November with my second baby. With my first we had boy and girls names picked out. My first little one was a girl and her name is Everleigh (now 4).

With this pregnancy we have done the same as I did with my last pregnancy (found out what we are having and told people we don’t know and are waiting)

We found out we are having a boy and me and my husband have said we wanted to use the name we would have used if my first baby was a boy (Douglas Arthur) as we love the name and I’ve never been put off it even after 5 years.

The problem is my cousin has just had a baby and used the Arthur as middle name for their baby.

Is it weird if I still use the name Arthur for my baby’s name?

My husband said it isn’t and he doesn’t care as we rarely see them.

I just didn’t want anyone thinking we picked the name because they did if you get me.

Help!
