In 1865 Felix Wilson died and "Tocal" was willed by entail to (unborn grandson) David Wilson. In 1871 Charles Reynolds died and management and stud stock were transferred to his widow Frances and their sons. In 1907 "Tocal" was sold to Charles Reynolds' son, Frank Reynolds. Frank died in 1920. Sons, Darcie and Arthur Reynolds ran the "Tocal" property as the estate of Frank Reynolds from 1920 to 1926. In 1926 the property was sold to the Alexander siblings (Jean, Isabella, Robert and Charles Boyd (C.B.)), who ran it as a breeding and dealing property. In 1938 Jean Alexander died leaving Charles (C.B.) on his own at "Tocal". The following year Myrtle and Marguerita Curtis came to "Tocal" to live with their uncle Charles. The Alexanders were a much more private family than the Reynolds. The departure of the Reynolds left a void in the social life of the district and led to a misconception that the Alexanders were snobbish. The Valley garden was a favourite spot of Myrtle and Marguerita Curtis. It most likely dates from the Alexanders' time, and displays the style of garden favoured by early settlers, based on familiar English plants. The last of the family, C. B. Alexander, died in 1947 leaving a complex will for the estate which among other things, left his properties (this one included) to establish homes for "destitute, homeless and orphan children" - in time this would provide for the establishment of an agricultural institution at Tocal. He gave his nieces, Misses Myrtle and Marguerita Curtis life tenancy and they lived at Tocal Homestead until 1985, dying just five days apart. In 1963 a solution to Charles Alexander's will was found by Edward A. Hunt, and work began on the construction of an agricultural college. The C. B. Alexander Presbyterian Agricultural College was opened by the Presbyterian Church on Tocal Homestead land in 1965. In 1970, management of the college was handed to the New South Wales Department of Agriculture, and the college was renamed the C. B. Alexander Agricultural College. In 1981, the Department of Agriculture's external study program moved to Tocal. The Tocal Field Days began in 1984. Upon the death of Myrtle and Marguerita Curtis in 1985, the contents of the homestead were bequeathed to the college. Since then the homestead has been run and operated by the C. B. Alexander Foundation.
