It is assumed Robert Mathison (husband of Jane Fairbairn, 1820-1885) and Janet Mathison (wife of David Fairbairn, 1847-1881) were brother and sister. This probably explains why David Fairbairn and his son Robert James Fairbairn are on the same gravestone as Jane Fairbairn. The blood relationship between David Fairbairn and Jane Fairbairn was 1st cousin, once reomved. David Fairbairn was also the husband of Jane Fairbairn's sister-in-law.
Robert married Jane Fairbairn, daughter of James Fairbairn and Jane Anderson. (Jane Fairbairn was born on 17 Jan 1820 in Cockburnspath, Berwickshire, Scotland, United Kingdom,34 died on 22 Oct 1885 1 and was buried in Cockburnspath, Berwickshire, Scotland, United Kingdom.)
