For your info if you don't already have it.
There is no record of this family in 1871 census that I can find.
The 1861 census has Edward age 35 at PI in Malew with wife Elizabeth age 35 a Catherine Corrin age 43. Then chilren a Robert age 7, Thomas age 5, Margaret age 3, and a John age 2. I don't know what the PI means but it is under district.
You have the 1851 census with Edward in Darbyhaven age 25 with parents Thomas and Margaret Cubbon along with his sisters Margaret age 37 and Elizabeth age 17.
The 1841 census has Thomas Corrin age 50 at Darbyhaven Fisher with wife Marg age 50 and children Marg age 25, Ann 18, Thomas 15, Edward 12 and Elis 8.
