According to legend, the Scottish clan Erskine were granted their surname by King Malcolm II after an ancestor of theirs killed a Danish general in battle. He apparently presented his bloodied knife to the king and said "eryskyne" (or "air an sgian") meaning "upon the knife", and the king made that his surname in honour of his valour. This seems a bit unlikely as an origin, especially as there’s no reason to doubt its origin as a habitational name, but it’s a fun story nevertheless.
First heard of this name through Diana Wynne Jones' book Archer's Goon. Thought it was made up until I saw it here.

I like this name, I always had a preference for rare names. If you name your child Erskine, you can place a safe bet that your child will be the only person in the school named that.
Erskine Caldwell (1903-1987) was an American author whose writings about poverty, racism and social problems in his native South like the novels Tobacco Road and God's Little Acre won him critical acclaim, but they also made him controversial among fellow Southerners of the time who felt he was deprecating the people of the region.
I'm not really sure why I like this name. It just has some sort of charm about it that isn't normally found in boys' names. Maybe it's the final "E" -- I like "Peregrine" as well.
