Several years ago I purchased a copy of an sketch done of the residence and cooper shop of Henry Onstot.The caption says that "Abraham Lincoln and Henry's son Isaac were friends and studied together . . ."The sketch was done in 1968? by a woman from Petersburg in Menard Co., IL so I presume that was where this shop and these Onstots were located.I'd like to send this to someone who descends from or is researching this Henry and/or Isaac Onstot. Please contact me by e-mail rather than on this Forum.
