Whitelaw is a surname of Scottish origin, derived from the Gaelic 'Fionnalagha', which means 'fair-haired'. It was traditionally a Highland clan name and may have been borne by many early Scottish families. The name first appeared in records during the 13th century and has since become quite rare, with very few occurrences today.
"Between 1892 and now, there were only five people named Whitelaw born each year on average."
