Logan County, Kentucky
In 1817 Isaac and James Marrs accompanied by Thomas Wagnon on a hunting and exploring trip into northwest Arkansas. They explored the area where Rhea, Prairie Grove, Cane Hill and Lincoln are located, making a map of the streams, springs, and mountains.
Isaac Marrs was more concerned with the map than the others, as he said that he was going to settle some day near the creek (later called Marrs Creek) where he would build a sawmill.
It would appear from this account that Rachel C. Marrs may have died on this trip to Arkansas. This was compiled by "4 sisters", it was published in 1965. More information is obtained from "Flashback", Washington County, Arkansas.
