Carey, I can help you get started. Wm Henry is s/o Israel Putnam Malott (7 Jan 1832, Highland Co, OH - -?-) and Frances Ann Eaton (25 Jun 1839 - 4 Nov 1902). Israel is s/o Michael Blue Malott (11 Dec 1806, Clermont Co, OH - 12 Oct 1889, Williamsburg Twp, Clermont Co, OH) and Delilah Chaney (11 Sep 1811 - 30 Sep 1842). Michael is s/o Daniel Malott (31 Jul 1780, Washington Co, MD - -?-) and Susan Blue (19 Jun 1779, Va - 8 Jan 1871, Clermont Co, OH) Daniel is s/o Theodore Malott (7 Dec 1755, Frederick Co, MD - 10 Mar 1845, Brown Co, OH) and Ann Lane (no dates on her). Have more on back when you are ready. All the Malotts you found are probably cousins as several Malott brothers settled there in very early 1800s.
Please verify all the dates I listed in case I made a typo or copied an incorrect date.Which of William H's line are you descended from?
