They are using the generic ancestors. Such as if you have red hair, you will refer to other red haired people as your ancestors. Because you share the same trait. I have never got the impression that he was refering to a blood line. Even when Trubel ask if they where related. Nick replied somewhere  in the past. indicating taht Nick believes that all Grimm steem from a single source. the original ADam and Eve of Grimms.
