Robertsen is a Danish patronymic surname meaning "son of Robert". It is part of a broader family of surnames across Germanic and Scandinavian languages, such as The equivalent English surnames Roberson, Roberts (meaning “son of Robert” or simply derived from the given name) and importantly, Robertson share a similar structure and origin. Interestingly, related English surnames like Dobbs and Dobson are also patronymic forms of Robert, where the initial 'R' evolved into 'D' through the common medieval English diminutive Dob (a rhyming variant of Rob).
Etymology
The ultimate root is the Old Germanic name Hrodebert, composed of the elements hruod "fame" and beraht "bright", thus meaning "bright fame". Introduced to Britain and Scandinavia by the Normans, Robert replaced the rare Old English cognate Hreodbeorht. In Denmark, the patronymic suffix -sen was traditionally attached to the father's name to indicate lineage, producing Robertsen.
