We don't know that it is a lingering memory.

Again, identical family exists in the Whoniverse, even for characters who (as far as shown) didn't have children, like Gwnyeth. But somehow hundreds of years later, an identical relative with a near identical name appears in modern day. The phrase and name have just as much possibility of being passed down through familial relation as they do for being the same woman. You can in no way prove that it's a carried over memory. There is no cold hard evidence for her being the same person.
