Richard's name is reasonbly well established from his son Charles and likwise his wife Mary.
Only one suitable marriage of Richard and Mary has been found, with fairly complete records.
Only one suitable baptism for Richard has been found 
and only one suitable burial.
Thus whilst the records may be implete his details are reasonably well established.
  

Possible Norfolk baptisms from 1770 to 1790
Richard Bayes Russell - 25 Apr 1773 - St Stephen Norwich to John and Eleanor
Richard Russell - 18 Sep 1783 - Wells to John and Mary 
Richard Russel - 12 Dec 1778 - Fakenham to John and Amy

Possible deaths of Richard Russell
Family search 1770 to 1843
Richard Russel, Wells - 28 Feb 1787
	register states - Richard son of Jno and Mary Russell / Framington Sp (appears to mean spinster, ie maiden name) - infant.
Richard Russell, Fakenham - 3 Aug 1834 - the register gives his ages as 56, so born 1778.

Although this is limited information it appears that the son of John and Mary Framington died in infancy.
The parents of the Richard (IND0052) would therefore appear to be John and Amy and he was baptised at Fakenham.

There are no suitable Richard Russells in the 1841 Census in Norfolk.
