This is one of my favorite names, it will definitely be part of my future son's name. I love this name with the nickname Dair, as Dair reminds me of the word Dare, and well, it sounds daring and makes a cute nickname!
I love the name Alasdair. I think it is very underused. I think of it as being high on the socioeconomic ladder yet still very approachable. I will definitely include this name some how into my possible future son's name.
