Continuing P. H. Aydon:
He appealed to the Victorian Parliament (Parliamentary Debates Vol. 67, 1991, pages 1821-4) because his name had been omitted from the list of permanent employees of the Hobson Bays Railway Co. when it was taken over by the Victorian government in 1878. It appears that it may have affected his retirement - perhaps a pension - in some way. He would have been aged around 65 by then. Interestingly he (called Henry Aydon here) was described as follows- 'He was one of these mild-tempered Englishmen who were not aggressive enough to assert their rights.' (page 1822).
Other facts listed on his Vict. Railway records - his marital status is given as a widower, and there is another comment St. 20.9.65? - perhaps a reference to when he began working for the Hobson Bay Rail. Co.
He must have been working for them when Agnes died in 1875 because it shows her husband, Philip Henry Aydon, as living in Sandridge then (a terminus of the Hobson Bay Rail. Co.). There is no suggestion on her death cert. that she ever remarried, or presumably P.H. either unless his second wife had died also).
Henry/Philip (seems to have used both names at different times) and Agnes were married in Eagle Hawk Gully on the outskirts of modern Bendigo - a major goldfield in 1853. I visited there a few years ago - the bottom of the gully is now a park. Archibald was born in Ballarat, and Frederick in Acoca, so the family must have moved from one Victorian goldfield to the next during the 1850s.
