A HISTORY OF SHENANDOAH COUNTY VIRIGNIA
by Dr. John W. Wayland
(there are photos you might want to see....)
(I am going to condense it a bit)
In August of 1764 eight Indians and a white man came into the Valley, crossed the upper end of Powell's Fort, and descended upon the home of John Roads, a Mennonite preacher and one of the Massanutten pioneers. The Roads homestead lies in a crescent bend of the South Shenandoah, on the west side of the stream, about five miles northwest of Luray, and directly south of Kennedy's Peak. Bixler's Ferry on the river is near by.
Rev. Mr. Roads and his wife, who was Eve Albright, had a large family of children, some of whom fortunately were not at home when the savages came. Mr. Roads, his wife, and a son were killed at or near the house. Two of the boys were in the cornfield below the house, alongside the river. One of them climbed a pear tree about 150 yards from the house, was discovered and shot in the tree. The other attempted to escape by crossing the river, but was pursued and killed in the stream. To this day that place in the river is called the "Bloody Ford". In the meantime Elizabeth, one of the older daughters, caught up Esther, the baby, in her arms and ran with her first into the barn, thence into a field of tall hemp below the barn, and so on to the river, excaping the vigilance of the Indians. Carrying the child across the river she finally reached the house of a neighbor, Esther grew up and married Dr. Jacob Kaufman. Elizabeth...married Jacob Goehenour. Two boys and two little girls were taken captive and led away northward into the Massnutten Mountain. There one of the boys and both of the girls were killed. The other boy, Michael, after about three years with the Indians, was allowed to return home. He married Ann Strickler, a daughter of Benjamin Strickler. In all, six of the Roads children were killed; seven survived.
Kercheval gives the year of the Roads massacre as 1766, but the tradition in the family has preserved the year as 1764.
(and it goes on to talk about the descendants of the Rhoads/Roads family in 1924 having a reunion, etc. and a memorial was erected at that time to the ones killed in the family).
Thought this might be of interest to you. Since two of the Rhodes boys were released in Nov of 1764, it would seem this all happened earlier than the family claims, or else the boys did not stay 3 years with the Indians.
