I wonder if it would be worth contacting these people to see if they can give you some ideas on where to search:
http://blackcountryhistory.org/subjects/You might need to define a time frame to search for Samuel in the UK, so it might be useful if you knew when he came to Australia.

Do you know?
As the family worked in the Tube Works and in 1871 aged 13, Samuel was a labourer there, and the family had many children, they were probably living in employer provided housing living hand to mouth. Unless well off or criminal there is unlikely to be any newspaper reports or paper trail of any sort for this family. I would stick my neck out and say that a drummer boy is not likely to get a mention anywhere, unless the band won competitions perhaps.

But this is out of my area of expertise and others may know differently.
Good luck.
