I have a copy of an article from a history of Randolph Co., Indiana which has an article about a Meshach Lewellyn who lived in Washington Co. PA before 1816.
Meshach was born sometween 1760 and 1765, probably in Loudoun Co., VA.He was the son of Shadrach and Deborah (Burson) Lewellyn.He married Hanna (Brooks?) ca. 1790, probably in Washington Co. (the article says Ohio, but it probably should be PA)During his moves west he lived in Washington Co., PA, Hardin Co., KY and Preble Co. OH before coming to Randolph Co., IN in 1816.
There is further information on his family which I will enter if you can use it.
