I found Robert Lindley and Mary in the 1880 census (MO - Wright Co - Boone TWP)
Mary - 43-TN-TN-TN
Martha A. -17-AR-IL-TN
Mary J. -14-MO-IL-TN
Living next door is James Lindley (I think maybe Robert's brother ?)
I found a James Lindley and Marth Patricia Hargus m. 14 May 1871 in MO at Ancestry.
You have Sarah Lindley daughter of Robert born in 1863, yet the 1880 census lists her as 9 putting her birth about 1871.
