Rites Set for Margaret Glenn Cornett, 80 : Pioneer: The former teacher was the daughter of Earl G. Glenn and Nina Mansur Glenn and granddaughter of Carlos F. Mansur, who became the county’s first treasurer.

Memorial services will be held at 1 p.m. Thursday at Trinity Episcopal Church in Orange for Margaret Glenn Cornett, a member of a pioneering Orange County family who died in a Leisure World convalescent home Saturday. She was 80.

A native of Santa Ana, Mrs. Cornett was born Margaret Leticia Glenn at Santa Ana Valley Hospital on Sept. 20, 1910. She was the daughter of two other longtime Santa Ana residents, Earl G. Glenn and Nina Mansur Glenn, and was reared at the family home on the corner of 18th Street and Broadway.

Mrs. Cornett was a 1927 graduate of Santa Ana High School and later graduated from Santa Ana Junior College (now Rancho Santiago College), UCLA and UC Berkeley. After earning a teaching credential, she began her local career at Santa Ana High School and later taught at West Orange Elementary School for 21 years.

She married another Santa Ana High School teacher, Royce Cornett, who died in 1963.

Mrs. Cornett’s mother was the daughter of Carlos F. Mansur, a Civil War veteran who settled in Santa Ana in 1876 and later became one of the founders of the Orange County Savings Bank. After helping establish the county as it broke away from Los Angeles County, Mansur was elected its first treasurer and served two terms, according to county historian Jim Sleeper.

Mrs. Cornett’s father settled in Santa Ana in 1888 and worked as a printer for the old Santa Ana Herald and Santa Ana Morning Blade. In 1895, he joined J.A. Hankey in the bicycle business and, after serving in the Spanish-American War, worked for the Post Office as a mail carrier for 33 years. He was also a member of Santa Ana’s volunteer fire department for 24 years.

After moving to Leisure World in 1973, Mrs. Cornett served as a volunteer at Saddleback Memorial Medical Center. She and the rest of her family are members of the Orange County Pioneer Council.

She is survived by her brother, Fred Glenn of Tustin; sons Lee Cornett of Villa Park, Tom Cornett of Columbia in Tuolumne County and James Cornett of Westchester, Pa.; four grandchildren, and one great-grandchild.

The family requests that donations be made to the PEO Scholarship Fund, in care of Alice Ligtenberg, 658 N. Clinton St., Orange.
