The following is from the stltoday.com website.
If you’ve seen the Gateway Arch in the opening titles of this season’s “Who Do You Think You Are?” (8 p.m. Tuesdays on TLC), maybe you wondered which celebrity would be investigating his or her family history here.
Turns out, it’s Chris O’Donnell of “NCIS: Los Angeles,” who worked with the Missouri History Museum as part of his episode of the genealogy series, which airs this week.
Thanks to my friend, Dennis Northcott, for alerting me to this.
