Barbara was born presumably in that part of Virginia that became Grant Co., West Virginia. Her parents were Martin and Mary (Wise) Hawk. In 1810 she married Jacob Cosner who inherited most of the Martin Hawk farm and Jacob assumed operation of his father-in-law's mill at what became known as Cosner's Gap near modern Maysville, West Virginia.
Jacob and Barbara were founding members of the Brethren congregation at Greenland Gap and it was on part of their land where the congregation built their "Brick Church" after the Greenland church was burned during the Civil War.
Jacob and Barbara were buried on their farm just west of Rt. 42 close to the "Brick Church" near Maysville, Grant Co., West Virginia. This property was the home of their grandson Simon Idleman at the beginning of the twentieth century and of Idleman's granddaughter Dorothy Browne in the latter years of the century.
