On the 1881 census Charles Smith aged 29 born Bridgnorth, a labourer, was married to Fanny and living in Walsall.
What do you know for certain about your Charles Smith - the first census for instance you know for certain is him? What information does he give about his father on his marriage?
Smith is an extremely common surname so you are bound to get more than one William and Charles of roughly the same age in the same place, if not several.
