I don't have any information on this line of Johnsons but I do have the couple Agnes Clark and Benjamin Johnson in my database. I am researching Clarks. Agnes Clark was born about 1716 and died around 1754. She was married around 1728 to Benjamin Johnson. Agnes was the daughter of Christopher Clark and Penelope Johnson. This line of Clarks are distant cousins to my own. They emigrated to Campbell and Charlotte Cos. from Louisa County, VA. These Clark lines repeatedly used the names John, Christopher, Francis, Micajah, Edward, and Robert making them extremely hard to follow. It is not unusual to find 3 1st cousins with the same common names.
