Diana Jill Siebert passed away in Oklahoma City on Saturday April 22, 2023, at the age of 61. Jill was born June 17, 1961, in Cheyenne, Wyoming, as the third of six children to Leo Siebert and Lois (Crane) Siebert.

As a military family, they lived a variety of places, including North Dakota, Georgia, and Germany. In March of 1979, when Jill's family moved from the Mississippi coast to Stillwater, Oklahoma, she stayed with her uncle Les and aunt Janet to finish her senior year at Pascagoula High School, after which she also moved to Stillwater. In 1983, Jill gave birth to her best friend for life, Lois Nichole. Jill and Nikki later moved to New Mexico and eventually returned to Oklahoma. Jill held a variety of jobs early on but quickly found her calling helping others as a dental assistant. For the last three years she worked in the business office for Nowlin Dental Clinic in Elk City, Oklahoma, where, as was usual for Jill, she made many close friends.

Jill was preceded in death by her parents; numerous uncles, aunts, and cousins; and sister Mary Estelle Siebert.

Jill is survived by her daughter, Nikki Baker and husband Ryan; grandsons Colton and Easton Baker; siblings Robert Siebert (Philippines), Roger Siebert and wife Victoria Briseno (Austin, TX), Marsha Holzer and husband Gary (Malone, WI), and Peter Siebert (Sun City Center, FL); uncle Les Crane and wife Marilyn Keys Crane; six cousins, including Debra (Crane) Pedulla and Danna (Crane) Borders; nieces Brittany Hanson, Kira Mulder, and Kayla Cluck; six great-nieces and -nephews, one great-niece on the way; and a host of other relatives and friends.

Jill was generous, loving, and easy to love, and she is greatly missed.
