KK: /ænsˈɛstrəs/
A woman from whom a person is descended, especially one more distant than a grandparent.

Ancestress is formed from "ancestor" (from Latin "antecessor", meaning one who goes before) and the suffix "-ess" (meaning female). The word refers to a female ancestor, highlighting the lineage through women.
Think of an 'ancestor' who 'goes before' and remember that 'ancestress' specifically refers to a female ancestor.
