Thanks again for the information. I have now discovered that Joseph Richardson died in 1851 soon after retiring from the Police and that Amelia went onto marry again to another policeman, but that she also died in 1857.
The mystery I have is that Amelia was obviously married to a chap by the name of Irons. Do you have any ideas how I can find out when she married her first husband and where it was. On the 1851 census Amelia states Stoke Golding Leicestershire as were born. I have not been able to locate her in the 1841 census.
