family secrets

Family secrets are pieces of information deliberately hidden from outsiders—and sometimes from certain family members themselves—to protect reputation, avoid shame, or maintain relationships.

These range from relatively minor matters like financial troubles to weightier revelations about parentage, illness, or past misconduct.

The phrase carries connotations of burden and eventual disclosure: Every family has its secrets.

Family secrets often surface at funerals, during estate settlements, or through genealogical research, sometimes upending long-held assumptions about family history.
