from the "History of Butler County"...Sylvanus, on the other hand, remained at home, tilled the soil, and married as his first wife a Miss GILLESPIE, by whom he had five children, none of whom survive. After the death of his first wife, he married Miss Elizabeth GORDON, daughter of James. By this marriage were born William, who died in infancy; Keziah, who, as the wife of William WHITMIRE, died when nineteen years of age; Sylvanus, Jr., now a resident of Concord Township; James, now occupying the homestead in Centre Township; Alfred, now a resident of Clay Township; Almira, who died as the wife of Warren THOMPSON; Rebecca J., who is the wife of Samuel TURK, at HILLIARD's Station; Samuel, who died when a young man, and William (2d) who resides at Liverpool, Ohio. Please notice that his youngest son is William the 2nd, strongly suggesting that there was an earlier William. I believe the William in Maryland must be Thankful's husband.
