The scientific method has been used for over a thousand years to advance human knowledge in an orderly way. It is regularly applied to all branches of learning, not just those we think of as “science”. This simple method can easily be applied to family history research to break through brick walls using logic and critical thinking. These techniques are particularly important where direct evidence is not available.nnThis seminar introduces the method, describes how evidence can be evaluated critically and provides real examples to illustrate how the method can be applied to discover unknown relatives or evaluate whether other families are related to yours.
