I think the names sound great together. I love the name Nicolas and have also considered it as a middle name. It has no family attachment for me though. I like its after your grandfather.
Thanx thats my husband middle name. We tried to combine it with Nicolás since its my dead grandfather's name. But I dont know... I dont want the baby to hate his name as he grows. His surename would be Farmer.
I love the name jonathan!
