Melissa Etheridge discovered a few more surprises than she expected when she agreed to be part of TLC's genealogy series Who Do You Think You Are?
Etheridge says she agreed to appear on the show's season finale (airing Sunday, April 26th at 10 p.m. ET) partly because her wife Linda Wallem is close friends with one of the executive producers, and also because she felt there were some holes in her own family knowledge. "I knew stories from my mother's family," says the Kansas native, "but with my father I didn't know anything past his parents, so it was a delight to all of a sudden open a door to all these stories and be like, 'Oh, that's where my father came from?'" In Etheridge's case, the investigation -- which included a full year of research -- turned up ancestors in French Canada who, in a scandal, sued a man who impregnated but would not marry their teenage daughter, and a colonial American entrepreneur who included bootlegging in his array of businesses.
