Actually, you need to be careful if you start poking into your heritage / race. I recently discovered that every single one of the women in my father's lineage (straight back) were unwed mothers.
This is going back at least 300 years. They must have had a terrible time of it is my guess given the strict Lutheran mores of Scandinavia.
Of course my mother also had to get married because she was pregnant with me.
Do you think poly is a genetic variation?
Compassionate toward yourself, you reconcile all beings in the world.
