Sharon Gail Erwin Null, age 66 of Arlington, Texas, passed away December 17, 2020 after a courageous battle with Lung Cancer. She was born in Killeen, Texas on December 29, 1953. Sharon graduated from L.D. Bell High School and attended Stephen F. Austin. She began her working career at Southwest Airlines before she dedicated her lifelong sales career to the eyewear industry winning several Regional and National awards before retiring. A very exciting time of her life was when she became a Dallas Cowboy Cheerleader in 1977 and saw the Cowboys win a Super Bowl! Her outgoing and gregarious personality meant that she never met a stranger and she will be sorely missed by the many friends that she has had the privilege of knowing throughout her life. Sharon is survived by her siblings, JoAnna Null Sweetser and Chris Null, along with Debra Spann, Cynthia Worrell, Lisa Whaley and stepsister Lavetta Ferguson as well as several nieces, nephews, aunts, uncles and cousins. The family has chosen not to have a funeral service at this time but would rather have a Celebration of Life to be announced at a future time. Memorials may be made in her name to the SPCA.
