I have been trying to find the story of a William Brideson who would have been born at about the time in the IOM, he is my Great Grand father, (so I am told) he is alleged to have arrived in Australia sometime in the 1860s, there is a very hazy background to his history, a Brideson disappeared from the IOM and another appeared in South Australia, I don't know if it is the same person as the one U are researching. Just out of interest have you discovered the history going back about 1100 years of the Brideson clan??

Funny thing I named my 2 boys Thomas and William before I started doing any family research.
