Hi Wendy, Have you considered the possibility that William may have been serving in the Royal Navy? Does their marriage certificate give his occupation as a seaman etc? In 1901, the Boare War was in progress, and having located my own family members' Navy records discovered they were at sea at the time of that census, hence their absence. There is an Eliza Wheeler on the 1901 census shown as head, I can't see the image to be able to tell you if she is recorded as single or married. She is shown as being born 1862 at Portsmouth, and is living in Portsmouth. It appears she is the only person in that household. Would you have been expecting to find any children with her by that time? Hope this helps in some way, kindest regards, Jon
