EZEKIEL PITTS - SC/NC TN IN

Can anyone provide me with additional information on Ezekiel Pitts and Lucinda Elder.It is believed they moved from Rutherford TN to Clay County IN where they are found in Census records.Lucinda's maiden name evidently comes from the death record of her daughter Elizabeth Pitts Killion.Can anyone provide me with a copy of that death certificate--evidently Indiana only provides to direct descendants.I need proof that Lucinda was an Elder as I am looking into the possibility that she was "Lucy Elder," dau. of James Elder and Mary Mason who moved from VA to Rutherford, TN before 1820. Lucinda may be the sister of my 3rd ggfather.Any info on this family would be appreciated. I will share what info I have.
