Not too much. But I have to admit,when we took a trip to Wales I understood things about my family that I never understood before. Like, why my mother and her sisters have olive-skin and brown eyes, given that their parents came from the British Isles. Turns out that a LOT of Welsh people have that same coloring. My father's family comes from England & Ireland several generations back. Out of the 5 of us, 4 have light eyes and brown or blonde hair. Only my brother has that olive complexion.
DH's family is from Greece. He is more interested in his heritage primarily because of his grandfather's story. Papa came over on a steamer at the age of 17 with no American money, no friends, and no English. He found work in a restaurant and slept on the floor in the kitchen becuase he couldn't afford a room. Eventually he saved enough to buy the restaurant. After he got a house, he married an American girl, bought up some rental property, and even had enough money to send some back home to Greece during WW2. It's a real American Dream story. Interestingly, Papa forbade his children to speak Greek or join the Greek Orthodox church. He felt that becoming completely American was his goal and that meant raising American children in an American life-style. THerefore, none of them really know much about their ancestors. DH and one cousin have done some digging and both of them cook
Greek. They both took classes at Greek School, so they speak a smattering of Greek, enough to get through a Greek Orthodox service, anywy.
