I am not researching this family, just entering information from one of my books, "Pioneers of Old Monocacy" by Tracey & Dern:"Two of the few Quakers who embarked in Indian trade were John and Edmund Cartledge from the Conestoga area of present Lancaster County, Pennsylvania.They traveled down Little Owens and Owens Creeks to what is now Stulls Ford of the Monocacy River, a route which eventually became known as 'Cartledges Old Road.'In the course of their travels they worked as intermediaires between the Indians and the Pennsyklvania authorities in efforts to maintain freindly and peaceable relations with Indian tribes and to govern white encroachments.Unfortunately in early February of 1721/22 while tracing rum for skins with a Seneca warrior named Sawantaeny, who was hunting on 'the Manakassy,' an altercation arose as a result of the liquor, and the Sawantaeny was killed.Reverberations were inevitable. (The authors give their source as Charles P. Keith, 'Chronicles of Pennsylvania from the English Revolution to the Peace of Aix-la-Chapelle, 1688-1748'.)
"John Cartledge died in 1726.Edmund lived on to become a taxable in 'Monocasie Hundred' in 1733 and at the age of forty-six appeared before the November Court of 1734.In 1737 he established a trading post known as 'Hickory Tavern' located where Sharpsburg in Washington County stands today.In 1748 he had land at 'Antietam Level,' now the site of Fort Ritchie."
John and Edmund Cartledge were on the 1718 tax list in Conestoga Township along with others who came early to western Maryland.
There were no other listings in the index on this name.
