Beecroft and Cheltenham were founded at a time of tuberculosis, cholera and the plague in Sydney.
Clarice Green a 9 year old girl died of typhoid fever in Beecroft in 1897. Because of its altitude many people moved to Beecroft in the hope that family members could recuperate in the higher altitude and dry air. Families who gave this reason for moving to the district included the Coward, Holcombe, Nixon, Pierce, Seale, Skellett and Vernon families.
The earliest local medical services were provided by a friendly society branch that was founded by the local station master in 1895. This friendly society arranged for a Pymble doctor, Dr Walters, to see members on Tuesday and Thursday afternoons.
