In my records, Paul Reed and Lois Stone Reed have a daughter whose name is listed as Diantha Blackman Reed. At first I thought that might be a middle name that was taken from an ancestor's last name. As I have done research, I'm beginning to believe that Diantha Reed married Lewis Blackman.
I have found Diantha Blackman in Macedon, Wayne, New York in the 1850, 1870, and 1880 Census records. She was born about the same time as Diantha Reed.
TODO: Look for land records or probate records that might list her as an heir to her father and mother's estate or connected in some other way to the Reed family.
1/29/2017: Searched grantee records for Wayne County: Grantee index v. A-C 1823-1869; Bla for Blackman, Lewis and/or Diantha. Could not find anything. Also looked through the BLs for transactions on Macedon. Still couldn't find anything.
