I'm seeking the same family.I'm trying to find Gilderoy's brother, James, as I believe my great-great-grandmother (Mary Westall Young Starner) was his daughter.Realizing that your message is two years old and you probably have this information already, I thought I'd still take a chance you were looking and pass on what I just found today:
(from:History of Fairfield and Perry Counties, Ohio, their past and present, 1883)
WESTALL, JOHN W., was born in Reading township, in November,
1832, and, excepting his two sons, Samuel and Frank, is the only one of this name left in the county, save his half brother, residing on the homestead, three miles west of Somerset.His great-ancestor, George Westall, was born in London, England, and after a 42 days' voyage, full of peril, landed in Rockingham county, Virginia, in time
to serve in the Continental army as a drummer.He had three sons---James, who died in Cumberland county, Illinois; Ambrose, who was a cripple from an accident in infancy, and Gilderoy, whose children by his first wife, Katharine Lidey, sister of Gen. John Lidey, were Samuel,
Joseph F., Eliza, Daniel A., John W., Rachel, Mary, Sarah, and George W., all of whom, except Rachel and Mary, settled in Lawrence county. Ill., these having settled in Whitney county, Ind. John W. Westall was married first in 1855 to Susannah, daughter of Jacob Petty, leaving at her death Samuel M., H. Franklin, and Susannah Katharine, an infant only two weeks old, at the death of her mother in 1861.
In April, 1865, he moved to Somerset and started in the grocery trade, which he wound up in 1876, after the death of his second wife, who was a Miss Berkheimer.His father, Gilderoy, came to Ohio in 1821, when 21 years of age, and was noted for his skill as a wrestler, a sport
not only peculiar to the Virginians, but much practiced in the early part of the present century in Ohio.His second marriage was to Katharine Montgomery, daughter of Rev. Joshua Montgomery, by whom he became the father of four sons and three daughters, who with their mother reside upon the old homestead.
