Hello Liz and also a thank you to Frances for your help with this.
I hadn't thought of looking to see if he rented any living accomodation, that's a good idea and also newspapers with regard to William Henry Cox advertising his business.
I just need a clue to find out when he arrived on the Isle of man, so anything that could help in that respect would be brilliant. Also as mentioned the name that wasn't very clear to read from the 1899 voters book if you can find out what that was it would be of great interest to me.
Thank you for sharing your knowledge of your island with me, I really feel like a fish out of water here, so thanks again for your valid help. I just wished the man had got wed on the Isle of Man it would of made things a lot easier, but never mind.
Ewan
