Baby name advice!

Sian

So my husband and I decided years ago that our first son would be called Samuel. And we just found out its a boy! 💙

So now we're on to middle names.

Husband has two, named after both grandfathers, I like this as a tradition, but both grandfathers would be Colin and Ian. Which kind of sound the same. Husband says we could just have one, or choose one and a new one. Only thing is my dad, Ian, died 2 years ago, and I would love to be able to honour him with using his name.

What do you ladies think?

He would be Samuel Colin Ian, or some other arrangement...
