I think your Irene Gallaway is from a different era in time. Irene Dabney Gallaway published her book in 1908. Her history is a family line that started probably in NC in the mid-1770s, and takes root in Oglethorpe (Wilkes) Georgia in 1790-1820. The Tait referred to was likely born in Scotland in the early 1700s, if he was the ancestor of this line of Gallaways.
