Well, the info you have found certainly ties up with what you knowdoesnt it. Travel company in Tonbridge Wells, ceased in 1996, and name Thomas Botting.
Would be quite a co-incidence for there to be 2 such people.
Would be worth looking to see if he left a Will in 1996 (too late for online records, but indexes can be viewed in person in Holborn, or a search done for you) - that may well mention his business interests and confirm (or otherwise) that you are on the right track.
