already own a domain - additional mailboxes?

[D3lirious]

I already have a domain and use office 365 business essentials for my email.

Is there a free/cheap way of setting up mailboxes for family members under the same domain? Can this be done so that their email is private, or is this impossible if I own the domain?

I don't want to pay full wack for additional 365 licenses if I can help it...

OK thanks guys, I'll look into additional licenses.

I think the privacy thing will be the dealbreaker anyway. It's a shame you can't somehow rent your domain out for people to use privately.
