Peel had been promised land grants if he arrived at the colony before 1 November 1829, and on arrival with the Armstrongs on on 15 December 1829 His other ships, and , were also carrying settlers so he was persuaded to accept an area of land named
Clarence, between the present day suburbs of
Mandurah and
Rockingham and inland to
Pinjarra. Armstrong was Peel's surveyor and he took up a parcel of land with good water to establish a farm on the
Murray River that he named
Ravenswood, establishing one of many Scottish connections. The family struggled to survive initially, in shelters made of wooden horse stalls, barrels and canvas, and eating food mostly brought by English ships. Attempts at farming were unsuccessful because of winter flooding and the theft of stock, so six families who had hoped to live there all returned to Perth and
Fremantle. Armstrong acquired land in Fremantle, lot numbers P99 and P84 around Thompson Street, Harbour Street Laneway and Quarry Street. He had befriended
Mark John Currie, the harbour master who lived on
Crawley Bay, and the Armstrong children were to stay there until their father found a better place. Armstrong had no money for provisions, relying on loans to buy food for his family. He was granted Swan Location 85 comprising on 18 September 1831. He dug the
water well that can still be seen at the site, built a cottage on the foreshore using limestone from the cliff, becoming
Nedlands' first European settler. The surrounding bush and pastureland was cultivated successfully by the Armstrong family, with Adam naming their new home
Dalkeith Cottage after the Scottish town where he grew up. When he came to sell his land in 1838, he had developed a farm of about on the fertile soil of the foreshore of
Melville Water. The farm vines were expected to produce of grapes and, as well as other fruit and vegetables, over of melons, while as a goat run it was unsurpassed. However, although the Dalkeith farm was successful and recognised throughout the colony, it could not grow wheat nor support enough cattle to sustain his family. In October 1853, Dalkeith Cottage of of land with a garden of was offered for sale or let, with vines and melons, with buildings and stock yard, to "be sold a bargain, as the present proprietor is going to the Murray". ==Later life==
