Form for creating/inviting new users

What I would like to achieve?

A form that enables a user creating a group of people on my website. Now: not every member of that group needs to be active (in other words: not every member needs to have an account on my website). You can think about it as representation of a family: adult members can have accounts but I let's say that I also want toddlers in my system and they won't have accounts.

So I need to give a user possibility to:

• invite other people by providing email addresses
• create inactive 'users' in the system only by entering a name

Please also note that it can be purely random fact that some users are 'inactive' (only with name) and others are active - for example it is possible that inviting user forgot (or doesn't have) email address of certain person so she/he provides only a name.

I am not sure how to create such a form... I think that it should be one view where I'm asking about those emails or names. Should I provide two fields (textareas), in one a user can provide email addresses and in another one a user can enter names of 'inactive users'? Something like this:

Do you think that this is good solution? Im worried that it can a bit confusing for users. Are those two textareas connected? Should I provide name for every email? and so on...
