I'm an expreienced researcher, but haven't before researched my very brief Blaise line. (I'm descended from William Blaise & Unknown spouse, through daughter, Sarah Blsise, wife of Marvell Moseley, and on down through the Daniel and Shelton lines.)
A court record shows William Blaise named son-in-law, Marvell Moseley, as his executor. Do you know if the will often mentioned, but not seen, even in trascription, by me, also names his son, James Blaise, as an executor? If not, this would indicate James Blasise was still a minor.
