The full family search citation was added. Full citation should be included so others can verify the information.
The initial 3 items in the Sources have the same year, which is not correct because the person could not be born, married and died in same year, but that is what the 'title' states for the marriage in the citation.
The full citation for Births and Deaths that was added is for a child of the person, so those do not appear to be a duplicate. Since the earlier ones have limited information, it is hard to know how, what or where they refer to.
