That's not really a spoiler alert, my friend. I just watched "Who's Alice?" (ep. 6), but given what I know of the timelines, it does not surprise me that Cora is aware of Anastasia. From the main show, we know that Cora disappears to Wonderland when Regina banishes her "Through the Looking Glass". (I like what they did there).

At probably around the same time is when Will tricks Robin into robbing Maleficent, and thus obtaining the looking glass that he and Anastasia used to get to Wonderland. So Cora and Ana probably rise to power around the same time (give or take a year). And since Will is refered to as the Knave of Hearts, I will presume that at some point in the past, he held that position in the Royal court of the Queen (Cora). So there was definite interaction, to some degree, between the 2 kingdoms.
