A surname; also potentially an obsolete or dialectal term (specific modern definition unclear in standard English dictionaries).
Likely derived from English patronymic naming conventions, with 'Gen' as a possible shortened form of a name like 'Gerald' or 'Geoffrey' plus '-son' meaning 'son of.' The term may be primarily known as a family surname.
Like many English surnames, 'Genson' likely started as 'son of Gen'—medieval people didn't have last names, so they'd use their father's first name, which eventually became the family surname passed down through generations!
