On FactGrid we created two properties for this (maybe clever, maybe daft): P290 and P291 for estimates (or for knowledge) of an earliest and latest point in the life span. The necessity is here that we have loads of people with just a single data point like "studied in Jena in 1776" or "appeared on a list of voters in 1849". If that is all you know, you do actually know that the person is likely to have a birth date some 17 (or in the voters case at least 21) years before.
If a person is only once mentioned as retired that stretches the P290 date to some 60 years before and so on - you qualify the estimate accordingly. I have no idea whether this is a good move on our site since we are not really that advanced in running the more intriguing SPARQL searches.
