The only record of Janet appears in the 1851 census for Kilmarnock, Ayrshire. In the household of William and Agnes she appears as a two year old daughter. No birth record is apparent, as her birth was prior to statutory registrations.
She does not appear in the 1861 census, and no record of death has been found between 1855-1861, presumably she died before statutory registration began in 1855.
