From a letter written by Oliver Coonrod, May 1917 in Washington Co, OH:
About the year of 1742, they came to this country from Switzerland or Baden, Germany and settled in the North banks of the Potomac River in the State of Maryland. The family of this history had one son born about the time they arrived in this country. They called him Josephas. After living a short time in Maryland they went to the South bank and from thence they journeyed up to Moorefield on the South bank of the Potomac in what is now Hardy County, West Virginia. They continued to push their way up the South Branch of the Potomac until in 1758 they were in Pendleton at a place now called Fort Siebut. In May 1758, after they had planted their spring crop, the heads of the families joined together and went a long distance to a salt works to lay a supply of salt and other necessities for their families to last the year. Before leaving for the salt works, they built a block house. The house was made by joining one house with another. There were about forty women and children left in the fort while the men went to the salt works. Among those in the house were five Coonrods; mother, two sons and two daughters. After the men had been gone for some time, a band of Shawnee Indians from the West of the Ohio River crossed over the Allegheny Mountains, and attacked the fort. The Indians set a siege of the inmated fort. They sent a flag of truce and said "if you will surrender we will spare you. If not all will be killed". To shorten a long story, when the Indians were let in a massacre ensued. The chief tried to keep his word and protected some of the women and children. The Coonrod women and children were spared but were taken away. The baby boy was killed during the trip to Illinois. Josephus got away. After 2 months he found his way home and found his father. Father and son followed the trail of the Indians and found that the mother had been turned over to the French at St. Genenever, Missouri. The father purchased his wife for $50. Mother, father and son returned to West Virginia."
Josephas married and had a son named Felix. Felix's son was Adam Coonrod and Adam's son was Oliver. Oliver is the writer of the letter.
