Terrence was the son of... Stockings vd Bijl and Andrezj Rogóz. (Dammit Bloom -.-)
Mask married Phělos (no last name) and has a son, Luneth. He married Lunaria (a girl with no last name), and had a daughter, Shana (LSZ character). Lunaria had a daughter with Lex Clark Sorcičre... this daughter is Shana's half-sister, Ciel (also LSZ character).
... Holy s**t, this family tree is VERY complex O.o
