Hayden or Dylan as brother for Euan?

[KLou111]

Hi
I'm 30 weeks tomorrow with a baby boy and we're really struggling to decide on a name!
With ds we'd decided before we even started trying!
The 3 we decided on were Hayden, Dylan or Jude, but have scrapped Jude I think now as we think it sounds a bit 'modern' (no offence to those with Jude's as we do absolutely love it!)
Anyway, our fave was Hayden but have always liked Dylan but it's become quite popular over the last few years.
Our son is Euan, so which do you think sounds better?
Our surname ends in 'son' (like Jameson).

We've said let's just wait until he's born and have a look at him but would be interesting to get other opinions.

Middle names will be John Phillip or Phillip John (doesn't matter which way). John as both my dad and FiL middle names are John, and Phillip as ds has called this one 'Pip' since he found out about him :)

Thanks in advance for opinions x

Haydn is Welsh, I think, and Euan is Scottish. Like them both but they are quite similar.

I prefer Dylan. Have you considered Hayward - different sound I know but has the same start. Know a newborn of that name and I really like.

I love Hayden, it's on our list. I like Dylan a lot too but feel like there are a lot of them around. So Hayden from me.
