Hi
I think you will find the answer to your question is no, especially as the Channel Islands come under two separate administrations - Jersey on its own, and Alderney and Sark coming under the jurisdiction of Guernsey - and not on the internet anyway.
If you go into nationalarchives.gov.uk and click on births,deaths,marriages link on the lefthand side of the screen, this will bring up a list of the Channel Islands with links to information to point you in the right direction to (hopefully) help you find what you are looking for.
Good hunting
