Summer Glau is an American actress. She is known for her roles on the shows Terminator: the Sarah Connor Chronicles, Firefly, The 4400, and Dollhouse. Summer’s father is of German/Alsatian German, English, and one eighth Swiss-German, descent. Summer’s mother is of English, Scottish, Scots-Irish/Northern Irish, Irish, and Welsh descent.
There are claims on the internet that Summer has Cherokee Native American ancestry, specifically from a great-grandparent. These claims do not appear to be accurate. While it is possible that Summer may have remote Cherokee ancestry, all of Summer’s great-grandparents are identified as “white” on United States censuses, and most or all of their recent ancestry has been documented as not being Cherokee Native American.
Summer is married to actor Val Morrison, with whom she has two children.
Summer’s co-star Grace Park has said:
She was really cool. We were joking that her name was Summer G. Lau and she was actually of Asian heritage – that’s what Daniel [Dae Kim] kept saying. I didn’t know that her ancestry actually is Irish and German. But yeah, she just brought it. There were so many takes where the camera wasn’t even on her, and she just gave it every single time.
Summer’s patrilineal line can be traced to her great-great-great-grandparents, Detlef Wilhelm Christian Glau, b. c. 1825, and Anna Friederike Basche, b. c. 1821, who were both born in Flensburg, Schleswig, Germany.
