I have Lewis as one of seven children born to Christian Mensch b. 1802 and Sarah Hursh b. 1803. Christian's parents were John Nicholas b. 1777 and Mary Yoder c. 1774. John Nicholas' father was Johann Christian Mensch b. 31 Jan 1744/45, Springfield, Bucks Co. PA and Anna Sabina Hess b.08 Feb 1753, Berks Co., PA. I hope this helps you.
