Names

Ive always been interested in different regions of the world and how they name their children, mums name, dads name, family name, middle names etc...and by searching the Internet for more information it seems that there are tons and tons or pages dedicated to naming children 'the British way' and that, apparently, we have a certain way of naming babies....I'm not so sure myself but it got me thinking.

This little one has a name and has had a name since he was a frozen embryo in an industrial freezer. His middle name has always been 'Raymond'...this isn't exactly my first choice of name but it's DHs beloved grandfathers name who passed away shortly before we began IVF and it seems fitting to use it. Sadly, at 14 weeks pregnant DH also lost his uncle who he loved dearly. This was completely unexpected and hit everyone hard, uncle was very supportive when we suffered our miscarriage and unfortunately died a few days before we told family our news which means he never knew he was going to be a great uncle. 

So we have toyed with the idea of using both names as Baby Bs 'middle names', but I'm not sure if it's too much on the poor guy? His name would then be M_______ Raymond William Briggs. Which is kinda long...

So what are people's thoughts? Two name too many or ok as it will only be used for formal purposes such as passports etc..?
