catch with splitting a discussion amongst 2 boards - however if he was a ltd company in UK then presumeably there would be some record in the companies register (you need register address, company seceretary etc) - likewise if he set up a IoM company, the records would be in the dissolved companies register - I've just checked Brown's 1894 directory which gives the proprietors of property - he did not own the property in Wellington st (most of which was owned by Eliza White or her estate) nor was there any public company (he was probably too small for this)
