The name Dickson is a boy's name of Scottish origin meaning "son of Dick". Dickson and discussed in our forums with posts like "Generation CAF #39 (British family w/ occupations)".
From the experts:
Dickson's nickname problem keeps it from having the upside possibility of similar names like Jackson and Harrison. If you're looking for fresh baby names to honor an ancestral Richard or Dick, consider Dixon. Or better, Richardson.
