Gayson

Gayson is a modern English surname-turned-given name. Like many 'son of' names (e.g., Jackson, Harrison), it directly indicates parentage. In this case, 'Gay' as a given name or nickname was historically used for both males and females, meaning 'joyful' or 'merry'. The addition of '-son' denotes 'son of', making Gayson literally 'son of Gay'.

The name's usage as a first name is relatively recent, emerging from the trend of using surnames as given names. Its unisex nature stems from the historical use of 'Gay' for both genders, though its contemporary perception might be influenced by the modern understanding of the word 'gay'.
