I'm pretty sure that River is more popular for girls - though don't take my word for it - however I prefer it for boys. It works find for a girl, and the imagery and the meaning and the colours etc etc are all very pretty and lovely, but at the moment I'm liking a lot of "girls" names on boys (Brooks, Sky, Devon, Phoenix) and River happens to be amongst them. River Amelie Rose is a lovely combo, although Rose continues to be bland in the middle. :)
River is one unisex name that I like on girls and boys.
I dislike most boyish names on girls, but I think cuz it is a word name, it doesn't bother me. I don't feel that it has a gender.
Your combo is quite pretty.
I think River has a very natural and calming feel. I don't identify it with one gender more than the other. It is more popular for boys in the US. It ranks #407 for boys and #686 for girls so it is definitely not overly popular for either sex and feels familiar on both. In my geographic area River is very overdone for boys. I would love to meet a little female River, and River Amelie Rose is amazing!!
Would be such a lovely name on a little girl.
River leans masculine but I like it on both genders. It is more common for boys in the US
I love River for a girl and your combo is beautiful.
