Mary Everall was born in Cradley, Worcester, England in 1791. She was the eldest child of Richard and Martha (Rhodes) Everall. A few years after Mary's birth Richard became a Nonconformist minister. He preached in the Independent chapels of several small towns in Shropshire for many years, finding time along the way to give Mary six siblings.

According to the IGI, Mary Everall and Thomas Morris of Isycoed, Denbigh, Wales, were married on 13 April 1819 in Malpas, Cheshire, England. They emigrated soon thereafter to Pennsylvania where they lived until moving to Muskingum County in 1832. For information about their children, see Muskingum County biography of Samuel McGinness, who married Sophia Morris, eldest daughter of Thomas and Mary (Everall) Morris.

All of Mary's brothers and sisters emigrated to the United States also. Two of them had ties to Muskingum County. One of these was Benjamin Everall, who applied for naturalization in Zanesville before "going south", never to be heard from again. The other was Mary's youngest sister, Bithiah Everall. Bithiah married John Butler Clayworth in Shropshire in 1845 and their son Joseph Butler Clayworth was born in Muskingum in 1847. Bithiah died soon after the baby's birth and in 1849 John married Jane Bratton in Muskingum.

Sometime between 1850 and 1860 Mary's unmarried sister Sophie Everall joined Thomas and Mary in Wayne Township.. A few years later, in 1865, Sophie accompanied Thomas and Mary on their move to Delaware, Tazewell Co., IL .

After Thomas died in 1867, Mary and Sophie continued to live together for a period of time. Between 1870 and 1880, however, Sophie moved to Farmersburg, Clayton Co., Iowa to reside with a younger brother and his wife, Richard and Elizabeth (Liversage) Everall. Mary died in 1885 at age 93; Sophie died in 1895. She was 97 years old, although she had lied about her age for many years and aged only seven years from one decennial census to the next. She passed on in the home of her nephew, John Everall, having outlived all her siblings, including Mary and Thomas Morris plus three brothers and their spouses with whom she had made her home at one time or another during the previous 50 years.
