There was an orthodontist at Newcastle Dental Hospital called Gordon Bennett Gillybob but I don't think it was him

It seems he was quite a character:
"It is reported that at the 1877 New Year's party held by his fiancee's father, he became so drunk that he mistook the fireplace for a toilet and urinated in it in front of his hosts and their guests. Whether or not that story is true is now difficult to verify. It is certainly the case that the marriage didn't go ahead and that the Mays weren't best pleased with Bennett - as this piece from The Perry Chief, January 1877, indicates:
"James Gordon Bennett was publicly horse-whipped this morning, by Frederick May, brother of the girl to whom Bennett was engaged to be married."
