We are heartbroken to announce the passing of Sheryl Lanette Yancy, our devoted mom,
nurturing nana, loving sister, close friend, and comforter and confidante to many.
Sheryl was born in Pasco, Washington in 1951 to Oba Clark Yancy Jr. and Dolores Dutro Yancy.
The family moved often during her early childhood, but eventually settled down in Texas,
where Sheryl enjoyed growing up with her two sisters, Linda and Vicki. Those who knew Sheryl
in her earliest years describe her as a tomboy with a sense of adventure and a penchant for
pranks. She was the queen of jump scares and scary stories. Her sisters describe their life-long
relationship as an unbreakable bond, with an ocean of love between them and their families.
As a teen, Sheryl met Terry Alexander through church, and they became close friends. The
friendship eventually took a romantic turn, and they were married on July 17, 1971. Over the
next decade, they welcomed three daughters: Christi, Cassie, and Cali. The family moved to
Colorado and enjoyed an adventurous lifestyle full of camping, fishing, boating, and hunting.
Family road trips to Texas, Lake Powell, California, Yellowstone, and more instilled a love of
travel in their children. Although Sheryl and Terry eventually divorced, the bond between them
was unbreakable, and their friendship and love for each other remained strong throughout
For the past couple of decades, Sheryl lived in or near Fort Collins, Colorado, near her children.
She welcomed sons-in-law and five grandchildren, and she thrived in her life as Nana. She was
an extraordinary baby-whisperer, cuddler, and bedtime-story reader. She was a devoted and
consistent fan at soccer games, baseball games, school plays, piano recitals, and more. A
second marriage, although it did not last, brought even more love into her life as she welcomed
two step-daughters and two more grandchildren.
Sheryl had a long and rewarding career with various environmental engineering firms in Fort
Collins, and was most recently working part-time for SLR. She was the queen of grammar and
worked hard as a document editor, office manager, coordinator, and just overall “office mom.”
Sheryl was a special person to everyone who knew and loved her. She will be dearly missed and
fondly remembered. She was our caretaker, companion, travel partner, movie buddy,
prankster, and broken-heart mender. She was our mom, our Nana, and our hero.
Sheryl is survived by her daughters, Christi Seidman (Marc), Cassie Cyr (Shawn), and Cali Oakes
(Tim); her step-daughters, Cindy Schenck (Dave) and Becky McFarland (Steve); her
grandchildren, Gabrielle Stokely, Alex Cyr, Tanner Cyr, Anna Seidman, Rowan Alexander,
Savannah McFarland, and Noah Schenck; her sisters, Linda (Cordell) Cameron and Vicki Yancy;
her ex-husband and close friend, Terry Alexander and his wife Helen Walser; her step-mother,
Judy Yancy; her step-sisters, Sherri (Johnny) Onesti and Jennifer Regan; and many nieces and
Sheryl was preceded in death by her parents, Oba Clark Yancy Jr. and Dolores Dutro Yancy.
