hmm....it is hard for me, cos I am not one of those people that thinks the first and second names need to 'go' with each other...I tend to find so many people pick first and second names based on how they sound said together in this sing-song voice lol The chances of the names being said together like that often at all are so slim (unless you are hypenating the first and second names)
So if they sound too sing-song together, I will usually not like them, whereas that tends to be why people choose them iykwim...

With that in mind, some thoughts! lol
