I am currently looking for probate information for Spence H & Manloff. I am a descendant of a few of Spence & Manloff's slaves-thus in need of any slave sells, Tax lists or probate info that could provide me with slave data detail. Let me know if you have any of this type of information or can point me to another genealogist enthusiast in your family that could help.
Thanks
