Elijah is lovely, it is getting a bit popular but it's so cute! I really like
Elliot better and think that it goes better with
Merrick but if you don't want two Elliots how about calling your son
Eli, or what about using something like
Elias,
Ellis, Ellison or
Elisha?
Elias Merrick or
Ellis Merrick would be so cute!
Elijah Merrick sounds great too! :)
