This is totally possible, but I should let you know the further you get into this field the less likely you are to be able to focus on two separate areas.

At the Bachelor's degree level you can usually study anything you want. Then if you move into the Master's degree level you would start to narrow your focus.

Finally, it is very unlikely to study these two areas once you have moved into the doctorate degree arena. During the doctorate level is when you narrow your focus even further than the broad topics of Ancient China and the Irish Potato famine, and begin to focus on specific parts, such as specific times and places in Ancient China or the Potato-Famine and its impact on the US.
