You can spin up wallets for friends and family:
Is there a way to connect multiple nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm wallets to one hub? Need a solution for my wife’s alby wallet.

I'm not sure if this can bring your wife's existing alby account into your hub or not; my wife runs her own lightning node so we have different alby hubs running on each node.
Yeah I’d be happy to set her up with a new wallet, but it doesn’t really say how to get her a lightning address to link to her nostr… 
It's pretty straightforward, in your AlbyHib go to the App Store and open the Friends and Family app up, put in the name of the person and it gives you several onboarding options (you need to choose one right away, as the onboarding options are only shown once. You can delete and recreate the family wallet if you aren't ready yet). I just did it with Alby Go mobile app and once you scan the QR it lets you choose a new alby lightning address.
Hopefully they update the guide soon because it just tells how to do a sub account but just says more to come on setting up a lightning wallet and address…
