Ladyhawk and Summercrush.
I had written this over a time and as I posted, I see you have posted L H.
I will still post though as it is slightly different to yours.

There is so much information here which has been posted/reposted/quoted that at times it can be difficult to follow.

Clifton is a separate registration district to Bristol and is now a suburb of Bristol.
You have parish records and marriages etc detailed elsewhere in this thread.
**Albert Eddy ‘disappears.
** Thomas Eddy is named in marriage records as father
**Thomas Eddy dies 1877
You have census 1871 for the Colemans
Nowhere is Cornwall mentioned as birthplace to Eliza.
We have tried to piece together your Norris information with the Eddy information through the various records.
Traditions were not always followed.
People changed their names.
People lived together because they couldn’t marry.
Sarah Ann married her partner Henry Coleman after Thomas Eddy’s death.
(My grandparents were together over 30 years before they could marry. They had to wait until her first husband died).
We are going round in circles with this information and you can try to verify anything with official records if necessary.
If you reject this family, then the Norris information doesn’t seem to fit either.
I am sorry that this is a much longer post than I intended. I have tried to summarise what is known about The Eddy family.
