My Robert Wallace and family were in Frederick Co., MD, ca 1790-1810. They had sons names Charles, William, and Robert (as well as John and Arthur), and a daughter named Margaret. I know that Charles married Anne Benton, and Margaret married Peter Shown, both in Frederick Co. There are also marrieges for a William Wallace to Elizabeth Hopkins, and a Robert Wallace to Jane Dwyre (both in 1799). I am trying to determine if these two, William and Robert, are sons of Robert and Violet Jane Wallace, and brothers to Charles and Margaret. Does anyone have knowledge of any of these folks???????? Thanks, Bob Wallace
