'Daniel’s and Nikita’s family': Possessive again…

[Tamara]

Hi

Belatedly doing my homework (writing essay for tomorrow )
I can’t write what I would like to write

Imagine that you are talking about two brothers, Daniel and Nikita (in Russian 'Nikita' is a male name).
How to use possessive correctly for 'Daniel’s and Nikita’s family' (not using 'their')
?

Hi Tamara

I'd say Daniel and Nikita’s family.

Happy homeworking.
