In 1861 Edward Pierson Ramsay was elected the founding treasurer of Entomological Society of NSW. He was a keen botanist who was friendly with the powerful plant men of the day, including William Macarthur of Camden Park and Alexander Macleay of Elizabeth Bay House. When Edward moved to Queensland to capitalise on the sugar rush, his plantation neighbour (at Tinana, Maryborough) was John Carne Bidwill, botanist and plant hunter (and Commissioner of the Wide Bay district), who discovered the Queensland kauri (Agathis robusta) and the Bunya pine (Araucaria bidwillii). In 1862 St David's Church Hall opened as a Sunday School and a day school, called Yasmar, during week days (the forerunner of Haberfield Primary School); Mary Louisa Ramsay was appointed Superintendent of the school. In 1864 the Ramsay brothers Edward Pierson, James and Percy purchased the Jindah sugar plantation at Maryborough, Queensland; Percy resided there. In May 1866 the first Divine worship was held in St David's School Hall, conducted by the Rev. Dr John Dunmore Lang. In 1867, Edward Pierson Ramsay opened the New Dobroyde Plant and Seed Nursery on the same Iron Cove Creek site as Dr Ramsay's Dobroyde Gardens Nursery. As a horticulturist he had much input into Victorian garden design and species registration. In 1874 Edward Pierson Ramsay, ornithologist and zoologist, was appointed the Curator of the Australian Museum (a post he held until 1894). He moved from Dobroyde house to quarters at the Museum. In January 1875 the Linnean Society of NSW held its 1st meeting with Sir William Macleay and Edward Pierson Ramsay original committee members. Ramsay became a fellow of the London Linnean Society and married Ellan Fox that same year. In 1877 Alexander Learmonth died in his garden at Yasmar, he was buried in the family vault at St David's Church. His wife Mary Louisa stayed there until 1891.  1882 saw the release of "The Dobroyd Estate" along St David's Road to St David's Church, being inheritance lands of Louisa Ramsay. In 1885 three further sections of The Dobroyde Estate were subdivided and sold for Victorian type residential subdivision near Parramatta Road (being Ramsay heirs Isabella's portions between present day Wattle/Alt Streets and southern end of Dalhousie/St David's/Dobroyd (now O'Connor) streets; and an area around Percy/Lord/Sloane/Marion/Hawthorne streets belonging to Louisa, Margaret and David Ramsay).
