Diane,
Many people could not read or write. It depended on who was writing it down and who was pronouncing it with what accent. You can be sure they are one and the same.
There are at least three possibilities for the Ellen you are looking for.
1. She was illegitimate daughter of Ellen Shannon
2 she was daughter of Joseph and Ellen
3 she was daughter of Joseph and his first wife.
It was not uncommon for birth registrations to be missing. Also it was possible that exact age would not be known by the Aunt and Uncle in the 1881 census,
