Abigail Loraine Hensel and Brittany Lee Hensel were born on 7 March 1990, Carver County, Minnesota, United States and they are dicephalic conjoined twins. Brittany is the left twin, and Abigail is the right twin. They have two spines which join at the pelvis. They have two stomachs, three lungs, and two arms.
