I have come across a website ......www.lightage.demon.co.uk which may help someone. Derek Wilcox has transcribed information obtained from old newspaper accounts regarding courtcases going back as far as the 1860's .
A Charles Shellard from Bristol is listed for the year 1864 under the section " Black Sheep Index".
There are also details from newspaper articles concerning servicemen who fought inWW1 and WW11.
An Edwin Shellard , Captain in the Gloucester Regiment was awarded the DSO in 1916.
