Looking for information on John S. Mosby who married Mary Johnson Winston July 20, 1822 in Louisa County Virginia. Daughter of Joseph Winston. Mary Winston was apparently married only a short time before she married John Todd Quarles Aug.4 1826. I assume John S. Mosby died. Her sister Elizabeth was married to Dr. Edward Mosby and had two children Joseph and Edward. Edward was bethrothed to Virginia Minor Quarles, daughter of Mary. Virginia and Edward would have been first cousins. Virginia died of typhoid at age 17. Does anyone have any information on this line of Mosbys. Who is this John S. Mosby?
