A Brief Biographical Sketch of William Gearing (c.1625–c.1690)

Since there isn't any biographical information about William Gearing available on the Internet, I thought I would fill that gap with information by Beeke and Pederson:

Little is known about William Gearing. He seems to have served as a minister in Lymington in the 1650s and later at Christ Church in Surrey. He preached a sermon at St. Mary Le Bow on September 3, 1688, in commemoration of the Great Fire in London.

Gearing published several works that reveal intimate awareness of the church fathers, experiential Calvinism, and the spiritual need of believers. His meditative treatise on prayer, A Key to Heaven (1683), is among the finest examples of seventeenth-century piety. He was also active in publishing some of the writings of John Maynard, a member of the Westminster Assembly.
