Sometimes we can be tempted to not look at every record, thinking that we do not need it or that information it provides will only be the same as what we already have.
Once I almost neglected locating a 1930 census entry for a family because "I didn't need it." Turns out I was wrong. It listed the "birth" name for a daughter, which ended up being a clue as to the name of the father's mother.
You just never know. And don't assume that you do not need a record just because you "know everything."
