That's another thing. Even if she's not his daughter necessarily he's still shocked to see her specifically because he obviously knows her. I can't see it any other way.
That's bare minimum.
I'd say the bare minimum assumption is someone who appears to want to be a Jedi just showed up on the doorstep of the guy whose last batch of trainees was killed by his nephew, who he was also training.
He's clearly been staying away from actively training anyone, so the prospect of having someone new to train would be terrifying and sobering all at the same time - whether he's related to her or not.
I took his reaction as "welp, I guess it's finally come to this. I'm so sorry for the destiny that has been thrust upon you."
