I can't find Richard in the 1870 census (he's not with Nancy), so I wonder if his death date is correct?

— born in GA, presumably in Habersham Co., GA:
  5.  Edley D. CORBIN, b. 1822/3
  6.  Samuel CORBIN, b. 1825/6
  7.  (Son A) CORBIN, b. 1825-30
  8.  (Son B) CORBIN, b. 1830-35
  9.  (Son C) CORBIN, b. 1830-35
10.  Emanuel CORBIN, b. 1837/8
11.  R. Jane CORBIN, b. 1840/1

Nancy states in the 1900 and 1910 censuses that she had seven children.  The only way I can see to fit in a seventh child is for there to have been a twin who died or that Nancy was pregnant when Richard died.
