Trauma is passed over generations.

Bakalar points to work by Santavirta et al. showing that the daughters of women exposed to childhood trauma are at increased risk for psychiatric disorders. The study compared the health of female offspring of ~47,000 Finnish children who were evacuated to Swedish foster homes during World War II, with offspring of female cousins who had not been evacuated. The study:
...found that female children of mothers who had been evacuated to Sweden were twice as likely to be hospitalized for a psychiatric illness as their female cousins who had not been evacuated, and more than four times as likely to have depression or bipolar disorder...But there was no effect among male children, and no effect among children of either sex born to fathers who had been evacuated.
