From an unnamed newspaper, Oct. 4, 1929 - " 'Aunt Peggy' Whitfield Passes to Her Reward -
Mrs. Margaret Whitfield, better known to every one in this section as "Aunt Peggy," died last Saturday morning at 11:30 o'clock, Sept. 28 at the home of her son Rev. Y. Whitfield at Pineville, with whom she has made her home for many years.
Her death was not unexpected, as she had been in feeble health for many months past and has been confined to her bed for some time. She was 87 years, 6 months and 13 days of age.
Deceased was born in this county and township, her birthplace being three miles northeast of here. All her life was spent here. Her maiden name was Langston. On November 13, 1856, she was united in marriage to Mr. Allen Whitfield, this happy union being broken by the death of her husband 23 years ago. As a young woman, Mrs. Whitfield united with the Cumberland Presbyterian Church, at Union congregation, with which she remained a faithful member till death, over a period of 75 years. She was a consistent and active church worker and stood ready and willing at all times to aid in any way in advancing the moral surroundings of her community and otherwise performing her Christian duty. Those who knew her best will remember through the coming years as a gentlewoman of loveliness and grace, possessed of fine principles and noble heart. Her passing is an event of great sorrow to the hosts who knew her and were associated with her through the years of a useful life.
The funeral was held at Union Church Sunday at 2 p.m., services being conducted by Rev. J. R. Jennings, pastor of Cumberland Presbyterian Church of Calico Rock. Burial took place in the nearby Tremble (Trimble) Campground cemtery. The largest gathering ever seen at that cemetery was present to pay late respects to the deceased.
Deceased is survived by three sons and four daughters - Jasper Whitfield of Little Rock; Casey L. Whitfield of Merriam, Kansas; Rev. Y. Whitfield of Pineville; Mrs. E. L. Sanders of Pineville; Mrs. Mary Moody of Iuka; Mrs. Tennessee Ivie of Cross Roads and Mrs. Alice Clark of Brockwell. Sixty-three grandchildren, 102 great grandchildren, 15 great-great grandchildren and a sister, Aunt Polly Hively, also survive."
