Helen was born March 17, 1926, in Vevay, Indiana to Bessie and James Rook. She completed school, attended church, had a singing group and worked as a waitress growing up in Vevay. After high school, Helen went to work at the shoe factory and then the post office. She met and later married Leon Lock on January 9, 1946.

Helen and Leon lived, worked and farmed outside Vevay. They had three sons during that time, James Elbert Lock, June 11, 1949; David Leon Lock, June 3, 1952; and Shawn Robert Lock, February 9, 1954. Leon transferred to White Sands Missile Range and the family moved to Carrizozo, New Mexico, in June 1959.

Helen worked at the Carrizozo Municipal Schools until her retirement.  Her last position was bookkeeper for the school district.  She then consulted for several school districts throughout the state.

The family attended First Baptist Church Carrizozo. Helen sang in the choir and eventually became the church’s song leader. She sang in a trio with Virginia Curtis and Joan Means and performed many specials in the church and for other churches.

They moved from Carrizozo to Roswell because of Leon’s medical condition, of which he passed. Helen was active in First Baptist Roswell where she met and remarried Darwin Alden Nelson, March 17, 2000. Darwin and Helen lovingly lived, traveled and took care of each other for twenty-three years.
