Hi Rosemary,
Can you provide more information? You said the women were living with their parents on the 1850 census in Hardy Co., TN. I don't believe there is a Hardy Co., TN. Did you mean Hardin Co.? Do you know their parents first names? In any event, I was unable to locate the family. Perhaps their surname was misspelled.
Also, you said the women married Coleman brothers sometime between 1850-1860 in Tishomingo, MS. Do you have first names for the brothers?
In 1870 Tishomingo Co., MS was divided into three counties: Alcorn, Prentiss and Tishomingo.
