Most of the Barbour family used the name Barber. The will is probated under that spelling. The will names "Nelson Barber and the children of David Barber Deceased, whose names or places of residence cannot after diligent inquiry be ascertained." The will was probated February 22, 1851. Our best guess is that he was still living in the Rochester/Dansville area in 1851.
The will and some other matter related to Friend Barber/Barbour was sent to us by a Babour descendant. Thanks Alice!
