Meaning and Etymology
The surname Robertson is a patronymic name derived from the personal name Robert, which comes from the Germanic elements hrod "fame" and berht "bright". The suffix -son literally means "son of", so Robertson literally means "son of Robert". This formation is typical of Scottish and Northern English naming practices. The name was first recorded in medieval Scotland and northern England, where it was used as a family name for descendants of men named Robert.

Subsequent records throughout the 14th and 15th centuries mention individuals named Robertson in various Scottish counties. These records confirm that the surname was in use by the early medieval period in Scotland.
Spelling Variants
Common variants of the spelling include Roberson and Roberston. These variations have been recorded in parish registers and civil documents, reflecting phonetic spelling differences in the 16th and 17th centuries.
How to Research This Surname
Researching Robertson begins with identifying the geographic region and time period of your ancestor. Because the name originated in Scotland and northern England, parish registers, tax rolls, and the Scotland's People online database are useful starting points for records before 1855. For later civil registration, the UK General Register Office and the National Archives hold birth, marriage, and death indexes. In the United States, the 1900–1940 Federal Census and immigration ship manifests can help locate Robertson emigrants from the British Isles. When consulting records, search for all documented spelling variants and be mindful of the transition from the patronymic "son of Robert" to fixed family surnames in the 16th century.
