William McFarlin died in Rutherford County, Tennessee, in 1824. His will lists his wife Sarah, sons Pleasant Nelson and Benjamin, and daughters Elizabeth Ann, Kasey, Nancy B, Louisa J, and Sarah. This appears to be the Elizabeth Ann McFarlin who married Robert Cummings. For a younger sister, such as Louisa J. was, to have come with Elizabeth and Robert Cummings to Texas was not unusual. It was also not unusual for a brother-in-law to witness a land grant application.
When Louisa J McFarlin applied for the conditional land certificate which she received, one of the witnesses was Robert Cummings. The certificate does spell her name as "McFarland" and the Minutes of the Board of Commissioners has this certificate under the name of "Louis J McFarland". But the certificate itself, now in the files of the General Land Office of Texas, shows the first name as "Louisa". Our Louisa J. McFarlin Long sold the certificate, after her marriage to Sam Long, proving that she was the owner.
