Lucinda Henderson and Lucinda J. Lane get confused as the same individual. Birth years and fathers have close names, and each may also have a sibling named William.
Little source information has been attached for the second profile, the 1880 U.S. census records show they are definitely different individuals, https://www.geni.com/documents/view?doc_id=6000000205134857827 and https://www.geni.com/documents/view?doc_id=6000000205133842938. The first individual was living with her father William John Henderson mother, and three children in Bell County, Kentucky. The second individual was living with her husband, two sons, and brother-in-law in Denton County, Texas.
Geni has suggested a match for Louisa Henderson and Louisa (Liza) Henderson They are the same person, but there are errors that should be corrected prior to a merge.
This individual is, in fact, the mother of the first profile, Lucinda Henderson. Lucinda J. Lane should be removed as a daughter of Louisa (Liza) Henderson
Louisa (Liza) Henderson records James Partin as a husband without providing any substantiation. His date of birth and date of death match those of her brother James Partin/Parton, who was married to her husband’s sister Delilah Henderson (see: https://www.findagrave.com/memorial/24101458/james-parton and https://www.familysearch.org/tree/person/details/K2XN-VGL). This profile should be removed as her husband and added as her brother.
Profiles were erroneously merged for William J Henderson, Sr. of Sumner County, Tennessee and William J. Of Claiborne County, Tennessee, son of Edward Henderson and Rebecca Henderson They were then removed and replaced as parents. Their son is now represented as William John Henderson It should be noted that Sumner County and Claiborne County in Tennessee are distant, so the likelihood of records for these individuals overlapping is quite remote. *These profiles should not be merged.* However the details provided for William J Henderson, Sr. probably belong to William John Henderson
