How are ancestors of step-parents handled?
I received a hint for an obituary for a person. When I click on "see relationship", he is shown as an uncle to the father of my grandmother. However, the 'father' is actually the third husband of my grandmother's mother, i.e., her step-father. My grandmother is the child of her mother and her mother's first husband. I feel as if I should only include the first husband and his ancestors in my family tree. Is this correct?
