Where did the name Arcadia come from?

One day last fall I was walking in the Chagrin Metro Parks, I got this peaceful serene feeling being in the woods and thought that this reminded me of being in the woods in Arcadia, a town in Northern California. Then I looked up the name and and found out means adventurous in Spanish. How perfect since we both love the outdoors and traveling. It was also an usual name that was easily pronounceable.Which is what we were looking for. So I asked christian what he though. It was the first name he also like. It happens to be a small town in Northern Michigan that Christian has found memories of going fly fishing in. So we both agreed on the name.
