Andrew Martin is owner and lead writer for History Repeating and Family Tree UK. He is a genealogist, historian, writer, photographer and archaeologist wanna-be. He also blogs. He recently posted on the Family Tree Bog, "History Repeating" about using censuses to find out more about our ancestors. Although his post uses an example of an 1861 UK census page, and the surprising information he gleaned from it, we might encounter the same "eureka moment" looking through the censuses of any country, county or other municipality. There was a time when families lived quite close together. Different surnames can indicate the families of daughters who married. Many generations often lived on the same block - or even in the same building.
I hope you will take a look at his blog post. I think it is relevant and hope you find this tip useful in your own research.
