Neil Campbell published his intention to marry Henrietta Campbell, daughter of Patrick Campbell of Kilduskland, on 17 June 1705, and he subsequently had four daughters and seven sons by her. One of his sons, Rev Colin Campbell, followed his father as Minister at Renfrew. Another, Duncan Campbell, took charge of managing the prison hulks, which transported the first prisoners to Botany Bay and another of which was sold off and became the famous HMS Bounty (formerly known as The Bethia). His daughter Mary " Mally " married William Richard Betham in 1817 and they were parents to Elizabeth " Betsy " who married Capt William Bligh, famous for the Mutiny on the Bounty. Neil Campbell seems to have inherited an estate - and minor title - near Inverary, called variously Clenary/Clenarie/Clonary/Clunary/Claonairigh. In 1744, he was appointed a Chaplain to the King, with joint share in the emoluments of the Dean, etc. of the Chapel Royal in Scotland.
