Daily Ancestorfiliaster
Filiaster is Latin for a stepson and also a son-in-law (filiastra: stepdaughter or daughter-in-law), so the meaning must be read from context.
Filiaster can mean stepson, son-in-law, or in some uses a nephew. The feminine filiastra means stepdaughter or daughter-in-law. The word is used where a family tie through marriage needs naming.
Because one word covers several ties, check the dates. If the person was a child when the other married, stepson is likely; if he married into the family, son-in-law is likely. Privignus and gener say the same things more precisely.
