I looked at your tree, there's a date typo in your post, *Dennis Connell( B 1923) of Tullyallen?*, should be abt 1823.
Roughing out a line is fine, but the work comes with filling in the blanks. The generation of Dennis Connell and Mary Golloghly's children have no birth/death, no marriages, this data needs to be filled in and documented. This is how you find clues to move back to the next generations with a good degree of certainty.

You'll have to expand on the specific sources you're using. That's the only way to help you/direct you to where you might find the documentation.
