Try researching Kansas. I show: Otho William Malott 27 Dec 1799 KY - 15 Apr 188_ Wyandotte, Wyandotte, KS (I show death might be 1881, 1882 or 1883) m. Margaret Beaty 18 Apr 1821 in Jefferson Co., KY. 10 Children.
I am sorry, but I don't have much on Margaret Beaty except that she died before 1880, prob. in Wyandotte, KS.
See The History of Lawrence, Orange and Washington Co.'s, Indiana, Sketch of the John W. Acoam who married Clara / Clarissa J. Malott. "Mr. Otho Malott, the father of Mrs. Acoam, came to Indiana about 1821. He moved to Kansas in 1878. and died there in 1882."
I would be interested in what you have on George F & Sarah Ellen Tyler Malott. I show they were married 01 Jul 1855 in Jefferson Co., KY and did not show any children.
