Kite - Originally I had Robert & Sarah as parents of Richard - and wondering why the dates were wrong, but you suggested that Robert was actually his brother (which I've altered).

The other Robert sounds feasible - the year sounds good (burial and age)

I'll add the other two children you mentioned, to Robert & Richard.

All I need now is when Robert (snr) was born, and who he married and when.

At least I've sorted (or rather you have) - the Robert's out!

I must say 94years old is pretty good for the early 1800's!
