A derivation from the last name of Gould which traditionally meant a person with "golden hair" i.e. blonde people. Gouldsons all seam to originate from the Wirral near Liverpool and unlike their scouse cousins they are not theiving scrot bags. On the contrary, Gouldson's rock!
Wow, that lad Gouldson, he isn't a theiving scrot bag scouser, and he also rocks!
