Eurasians who may have lived in the 1700s? (9)

'eurasians' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'may have lived in the 1700s?' is the wordplay.
I cannot quite understand how this works, but
'1700s?' could be 's' and 's' is found within the answer.
The remaining letters 'georgian' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'who' is the link.

Can you help me to learn more?
