Not that I know of. My earliest confirmed Corris is Patrick Corris b in Patrick (about 1790 according to census entries) who I believe to be the son of Thomas Corris and Margaret Watterson (but this is not confirmed). Patrick married Mary Kelly in 1809 in Patrick and later Jane Corkill in 1834 in German.
I'm interested in all things CORRIS though. I have a very basic website (due for an update a long time ago) where I have my tree and will soon be putting up a transcription of Corris entries in the IOM 1841 census. It's at: http://www.users.bigpond.com/rcorris/. There's a link to my email as well.
I'd love to hear about your Corris's or, if you have anything online, have a look.
Sorry I couldn't help with your William.
