In 1844 the Maitland Mercury reported - Raymond Terrace is a very prettily situated town, and one which has made rapid strides in improvement. It is finely situated as regards frontage, being at the junction of the Hunter and Williams Rivers, but the great drawback is the want of back country. This, however is likely in a year or two to be obviated, for the swamp at the back, which covers an immense tract, is in course of being drained by the spirited proprietor, R. Windeyer Esq. and I am credibly informed this will be accomplished effectually. When the undertaking is completed Raymond Terrace must go ahead'.
DEATH OF RICHARD WINDEYER
Richard Windeyer became ill in 1847 and while visiting relatives in Launceston to recover his health, passed away aged 41.
The estate was already in financial difficulty and was auctioned in twelve lots on Monday 28th August 1848, however Maria Windeyer continued in residence.
