Yes, James Woods looks like their grandson, and Robert next door could be Robin b.1810 - but Greg needs an age for husband (of Esther) Robert Corkill, to see which family he came from.
If he doesn't appear in 1841, yet died after Esther [MI], was there a Robert Corkill widower somewhere in 1851? Who could have had children born from 1805 onwards and been married to Esther who was b.1781?
And what happened to Robert bapt 11 June 1820, son of Peter Corkill & Elinor Clague?
