Jennings was born in the
Gila River Indian Community near
Tempe, Arizona but was raised in Oklahoma. Her parents were Clifford Santos of the
Gila River Pima tribe and LaQuinta Mopope, Jennings is the oldest granddaughter of
Kiowa Six artist
Stephen Mopope and Jeanette Berry Mopope, from whom Jennings "inherited the Kiowa songs, crafts, manners and language" that is integral to her artwork. Jennings began doing beadwork at age 11, after observing and helping her grandmother with her artistry for several years prior. As a child growing up in
Lawton, Oklahoma, she was often teased by others for wearing leggings and braids instead of trying to conceal her Native American heritage. She attended high school and college in Oklahoma. After graduation, she worked with the
Bureau of Indian Affairs and then moved to the allotment land granted to her grandmother in Red Stone, Oklahoma. She and her first husband built an
earth lodge on this Kiowa spiritually-significant property, which she uses as a studio and also makes available to the tribe for various cultural activities. In addition to her grandmother, another major influence in Jennings' life has been her participation in the O-Ho-Mah Lodge Society, a Kiowa war dance society with which her family has been involved for several generations. Her grandfather Stephen, his father George Mopope, and Jennings' sons Gabriel and Seth have all performed songs at Society ceremonies. ==Career==
