Just out of curiosity, I understand that the two accounts must use different email addresses. Would the second account need to have a different owner name? Would the account have to be under a relative's name or can I also have it under my name?
Yes to your question about two different email addresses. But beyond that, everything else could be the same. The email address is the only item that separates accounts from each other. But that also means that anything you subscribe to through Roku is only available on Roku devices that are registered to that specific user account. So if you wish to share a subscription on both TVs, the subscription has to be directly with the provider, and not through Roku.
When you live under the same roof as your parents, it's completely permissible to share a subscription with them. Providers like Netflix are now going after users who share a subscription but don't live in the same place.

I am not a Roku employee, just another user.
