Robert Halley was born in
Blackheath,
Kent, near
London. His father, Robert Hally, was a Scottish nurseryman at Blackheath; his mother was his first wife, Ann Bellows of
Bere Regis, Dorset. Robert Hally worked for a time at Luton Park, the estate at
Luton Hoo of
John Stuart, 3rd Earl of Bute. After marrying, he set up a nursery on land belonging to
Sir Gregory Page. His father, an
Anti-Burgher by background, was a deacon at the Butt Lane Chapel, where John Theodore Barker was the long-term pastor. Halley attended the chapel as a child. His parents had met in the Bere Regis
meeting house of Benjamin Howell, near which Robert Hally was working, and in which her father, a presbyterian draper, had a
pew. They were married in 1795, and Robert Halley was the eldest of four children. On his mother's side, Halley was a first cousin to William Lamb Bellows, father of
John Bellows. He was the son of William Bellows of Bere Regis and Elizabeth Lamb, who married in 1801 at
Wareham, Dorset. Ann Hally died while Robert was still young and he was sent to Dorset to live with a maternal uncle. He gained some classical tuition there from the parish curate. He returned a few years later to Blackheath to attend Maze Hill School in
Greenwich, where he was taught mathematics by a compass-maker from
Deptford Dockyard. Unsuccessful in applying to
Hoxton Academy, he was offered a place at
Homerton College in 1816. He studied under the tutorship of
John Pye Smith for a six-year course. After five years, it was Pye-Smith's colleague William Walford who discussed possible ministerial settlements with him. ==Pastor==
