I just don't think it goes with Silas-- Silas is so old and steeped in biblical history. I mean, it's from Aramaic! Arden is just some made up, newish sounding name. If your son was named Hunter, I'd say Arden was fine. But with Silas, I hope you will consider a beautiful old testament name with some presence: HannahLeahMiriamSarahRebeccaEveDelilahNaomiRachael
I LOVE the name Arden and if I were bolder, it would be DD's name. It is our top choice for a middle name this go-round.
I like Arden. I am one who like for my children's name to strike ME. And, while I value the input of others, I typically go with that unction -if you will. Almost everyone here detested my youngest child's name when I posted here...but to this day I know it was right for him!
