She or her? (She'll graduate next year. She and her brother live with me.)

I’ve heard both of the following in spoken English, but in written English which is more correct?:

[color=blue]1. She’ll graduate next year. She and her brother live with me.

[color=blue]2. She’ll graduate next year. Her and her brother live with me.

And what would be the best way to combine them into one sentence?

Thanks in advance,

Number 1 is correct. Number 2 is wrong. It is not “less correct”; it’s just wrong.

It’s hard to know how to combine them into one sentence unless we know the sequence of events. Is one happening after the other? Are they happening at the same time?

Thanks a lot.

She and her brother live with me, and she’ll graduate next year.

How’s that?

And is it better to say 'She’ll graduate next year" or “She’ll be graduating next year?”

Your combination is fine.

You can say, “She’ll graduate next year,” “She graduates next year,” “She’ll be graduating next year,” or, “She is graduating next year.” The difference is governed by the general rules for using those verb tenses.

Thanks again.

If you hope to help, I think you need to start punctuating your posts correctly.

As for combination of two sentenses can I say, for example, «She and her brother will have been living with me since she graduates next year»? I’m trying to use Perfect Future Continuous.
Or I have to use Future Simple in this case?
