Open Question: How is the 12th house tied to unresolved family issues?

This is a quote from an online astrology blog Ive been reading: "The 12th house may also have strong connections with inherited "family life issues" or "gifts" that our parents (and perhaps our parents' parents) were given... but they refused or were emotionally incapable of consciously giving expression to and/or resolving these "family life issues" during their own lifetimes. And now it's been left up to the child (you) to experience and resolve these energies for the parents." Is this true for your own 12th house placements? What skills/issues does your 12th house placement reflect?
