I'm not saying I believe any of this, but mathematically speaking, if the man is in his late 20s to early 30s and the girl is 10 that puts them about 20 years apart. Henry and Robin are two close in age. It could be Henry and his daughter, but if the two new characters are father and daughter, that means the man (possibly Henry) had his daughter at a really young age. If the man is Henry, the girl probably won't be born for a few  years. Although, I don't think the show can reset 15-20 years in the future. They would have to recast everyone and all the main characters would be in their fifties. 10 years might work. The girl could be Emma's daughter. I find it likely that Emma will have another child in the future since she is about to get married, still very young, and missed a lot of time with Henry. I also think Emma and Hook would be good parents together.
