Cubbon

In 1841 Robert Cubbon was living at Balla Kinnag Andreas with his wife Margaret, his age given as 70 and hers 75 and also living with them was Eliza aged 20 (ages rounded). Robert and Margaret nee Radcliffe married 7 Feb 1795 Bride. Margaret died 1845 aged 80. Robert died 1849 also aged 80, both Andreas (courtesy of Brian Lawsons site).
Can anyone help please with who Roberts parents were? Also who was Eliza Cubbon living with them in 1841? As far as I can ascertain Robert and Margaret only had one daughter Esther who married Edward Creer so perhaps Eliza was a niece?
Any suggestions please?
