The 14th British series of "Who Do You Think You Are?" featured Horwood's ancestry in the second episode. In this, his family history research took him home to Australia, where he discovered that his family tree traces to Gloucestershire, Lancashire and Essex in England. Horwood found out that he is not the first dancer in his family and that he is descended from gold prospectors that went bankrupt before becoming rich on finding a 250-ounce gold nugget. He learnt further that his great-great-grandfather, Moses Horwood, who is revealed in the programme to have been a petty criminal from England, was convicted at the Gloucestershire assizes and transported to Van Diemen's Land (Tasmania) in 1841. Criminal records identified by TheGenealogist include a transportation document for Moses Horwood, showing he departed England on 1 December 1841 on board a ship called the John Brewer.
