Miss Nora Craig, last week, spoke to 54 members of Forfar Probus Club on the Carnegy estates of Lour from the 1400s to the present day.
Nora, who has lived in Dunnichen since 1974, has always been interested in horticulture, having run a small nursery.
She has been helping with the gardens at Lour since 1981 and was recently invited to write a history of the Carnegy family.
She recorded the development of the farming estate through the centuries, from growing flax, barley and peas in Jacobite times before tatties were introduced in 1757 to the acquisition of 11 farms of 1800 acres by 1936.
The Carnegys of Lour served in the Indian Mutiny, the siege of Lucknow, and in Palestine, had shipping interests and were involved in the East India Company.
Nora also traced the distinguished career of Baronness Carnegy.
Ian McLean proposed thanks to Miss Craig for the excerpts from her book which gave a historical account of a famous local family.
