He had apparently been searching for her for years, and was the sibling who spearheaded the search for her, TooFab reports.

Tisha revealed that while they all share the same father, Ellen and Duane also share the same mother, a woman named Laverne.

"Duane is first born. Then my mother got pregnant with me and he married my mother," explained Tisha. "Then you came and Laverne never wanted to give you up for adoption. She cries on your birthday every single year. You look exactly like your birth mother."

Lindsey finally got the answers about why she was given up for adoption.

"She knew she couldn't give you the life with just being a single mom that she really wanted to give you and she had to give you up for adoption," Campbell-Martin explained. "And before she passed away, we wanted to find you so that you guys could meet and he's been searching since he was 18 years old for his sister."

The My Wife and Kids star explained that the search was tough.

As the adoption agency that organized the adoption and the hospital where she was born didn't exist anymore, the siblings kept hitting dead ends. She also added she didn't learn about her half-sister until she was thirty-three.

She then asked Lindsey what her life has been like.

"My dad's deceased. My mom is 90 now, she did an excellent job raising me," Lindsey said. "I went to college. I'm her only child, I'm spoiled."
