I like all these names for various reasons. Evelyn is probably my favorite girl name for a long time but it's too popular in the US. I didn't really like similar names that were always suggested if you like Evelyn you will like Elowen or whatever the suggestion was. I saw Elwyn and loved it almost as much then I found an Elwin in my family and thought that was so cool. Alvin is another family name I like and possibly why I like the others because of the similar sound.
I really like the sound of Alvin Ross for a boy. Evelyn is out for a first name but my brother who is done having kids thought about Evelynn. I wouldn't have thought of this because the weird spelling would have thrown me but it makes it like it oh so much more. My middle name is a mix of two family names and I love it so I would love to use Evelynn as a middle name for this same reason.
All of them would more likely be possibly used as middle names in any children we may have. What do you guys think of the names? Spellings? Are there any first names or combos that sound as good as Alvin Ross?
