Names that kind of rhyme?

Ok, hopefully this will be the last time I post in here about the names we have picked. Previously I have been undecided about the girl's name, but I think we've settled on that now - T a h l i a - A n n e (two words without the hyphen, just need that in there to separate the names cos of the spacing).

Now, I'm having issues with the boy's name. We have decided on M a x - W i l l i a m - J o h n (William after DH's grandfather and John after my grandfather), but I'm not quite sure. I think it's got something to do with the number of syllables in each name but I'm not really sure what the problem is. Anyway, I'm wondering whether either of the following might be better.
M a x - W i l l i a m - F r a n c i s
M a x - F r a n c i s - W i l l i a m

Francis is my grandfather (John)'s middle name and also the first name of my other grandfather. The only problem is that Francis rhymes with our surname, which (Mansen).

So, what do people think? Does the version with John sound ok, or does Francis work better? And if the latter, is the first or second option better and does it matter that it rhymes with our surname?

Thanks!

I like M a x F r a n c i s W i l l i a m best!!

Hmmm thats a hard one, William and Francis are fairly long names - I think Max John William sound so bold and strong, great for a boy. I think going from short to long seems to just flow a bit more. Or If you decide on Francis then I'd say Max F W Masen.
I'd also just like to add.. Max is sucha a gorgeous names and I really love William and Francis is a family for me too!
Good luck with it all.. Oh and beautiful girls name too :)

Max William Francis sounds fantastic!

Although I don't know if Max flows as well with your surname.

I like Max William John! :)

Thanks guys! Although I posted this with a hope of getting some strong views one way or the other, your responses have been just as good - convinced me that all options are good and we should probably just stick with what we had first decided!
