They had their own name at the time, and their names were just taken away later during their training. However, it was different from their current name. So, Tsubaki wasn't called Tsubaki back then. But yes, InTheRaccon is right, the information was collected from the minds of those she had controlled
For those unaware, this is not actually the first time Ashe has been mentioned. Just a little over a year ago, she was talked about in a fanmail question given to Tsubaki

Quick question: How would Ashe have known Tsubaki's name or had her own name? As i recall at that time in the village the servant core didn't have there own names
