Magnus, Marcus, Frederick or Ranulf?

[Sunnysummer]

Have been a longtime lurker here, as DH and I have been locking horns about boys names for so long! We have now decided to go with family names. Most of our family are from overseas, but names that we think also work in England are:

Magnus - we both like, but on mumsnet it seems very trendy right now?
Marcus - he says strong, I think weedy
Frederick - Freddie is so popular right now, would he be one of 10 at school?
Ranulf / Ranulph - the actual family names here are Randolf and Adolph, but we thought that these were too cruel! I like these names, but are they a bit too odd?

Also... My secret favourite is my great grandad's name, Leonhard (pronounced a bit like Lay-on-hart) but I don't know how an actual child would get on with this at school! My friends say that the alternative Leonard is weedy and Leo/Leon are getting too common in both senses of the word! So maybe it's out of the running...

I would be so grateful for your advice! We are living overseas now but will be back in London within a few years and don't want DS to get horribly bullied, or be one of 15 same names in the class! Any other suggestions also welcome, we like names that are traditional but not toooo common, DH likes 'strong' (whatever that means! But things like Caspian and Rafferty are way out), and nothing ending with -a/-er/-or as our surname ends with an -er and rhyming sounds terrible :-) Thank you!

Love them all, but in particular Ranulf and Magnus.
