Every week, celebrities make fascinating discoveries about their family history with the help of Henry Louis Gates Jr. On his PBS series "Finding Your Roots With Henry Louis Gates," the renowned Harvard professor has tackled the genealogy of actors, politicians and university presidents. He's even found a family connection between husband and wife.
This week, Gates is digging into the ancestry of domestic diva and talk show host Martha Stewart, comedian Margaret Cho and doctor and television personality Sanjay Gupta. All three guests are children of first or second generation immigrants and share the peculiar burdens of that heritage.
Find out what the three discover on Sunday night at 9 p.m. on PBS.
