Isabel Fletcher was born on May 12, 1862, in a log cabin located on the present site of the school bearing her name. She was the daughter of John Fletcher and Katherine McLaughlin of Glasgow, and was the first girl born in Korah Township.

Isabel Fletcher received her early education from her mother, and later took government correspondence courses.

In 1881, Isabel Fletcher married Joseph Sharp of Prince Township. The Sharps made their home in Prince Township, near the township line separating Prince from Korah, and continued to live there for almost forty years. According to family sources, Isabel and Joseph had eight children: Frannie, Katherine, Charles, George, and Leslie, Harold, Bessie, and another girl, who died in infancy.

Isabel Fletcher Sharp took pride in the work she, as a pioneer, was required to do. She regularly sold fine quality vegetables and butter at the farmers market in Sault Ste. Marie. Her butter was favoured in the community, and was easily recognized by its distinctive shape and wrapping. Mrs. Sharp was also known throughout the area for her ability to locate and gather wild berries. At first local fairs, her quilts and comfortorters so often took First Prize. Mrs. Sharp was active in Church work and in the Women's Institute.

Those who knew Isabel Fletcher Sharp remember her as a kindly, good-natured woman, Neighbours are quick to point out that she was always ready to help out in case of illness. In her later years, she moved to Sault Ste. Marie from Prince Township, and many children in her neighbourhood called her “Grandma Sharp”.

Mrs. Sharp passed away in December, 1940. In 1960, the new school at the corner of the Third Line and Goulais Ave. was named the Isabel Fletcher Public School. This name is not only to honor Isabel Fletcher, but rather, as is stated on a plaque at the school, is to honour all pioneer woman of the area.

Mrs. Isabel Fletcher Sharp is indeed a fine representative of the brave Korah woman who gave so much of themselves to their community at a time when the township was in its infancy.
