Can you help?

Whilst searching for new Cook-Abbott's to add to my family tree, I have come across a few individuals with only a single life event (birth, marriage, death etc.). They do not appear in the Name Index, as I have not yet been unable to confirm a link between them and anyone else in the main tree. Perhaps they are members of your branch of the family?
If you can shed any light on any of these people I would be delighted to hear from you.
