I know that several of us have been working on documenting the whereabouts of Andrew Jackson Langworthy and his descendants as well as his (and our) ancestors.Now that more death certificates are found online we are finding some serious errors in them.
Andrew's second marriage was to his sister's (Cordelia) youngest daughter, Bertha Sargent. The death certificates show incorrect fathers for Andrew, Bertha and Cordelia.Andrew's DC shows his mother as being his first wife, Emma.I believe the information was given to keep the surviving children from realizing the truth.
Please remember that the personal information on a death certificate is given by survivors or, in the event there is no family, it can be given by a neighbor or a friend. Use death certificates as a tool but don't trust them as a final authority.
