In the fourth Assembly, May 10, 1673, Colebeck was again returned under the general head of St. Catherine as chosen specially for Bowers. In the next Assembly, which met on February 13, 1673–74, his name appears as one of the three representatives for St. Catherine generally, the return omitting the former distinctions of one member for St. Jago, another for Sixteen Mile Walk, and a third for Bowers. In the sixth Assembly, April 26, 1675, he was elected for the newly formed parish of St. Dorothy, and continued until his death to represent that parish in every successive assembly, viz. on April 9, 1677, when he had been promoted to the rank of lieutenant-colonel; on September 6, 1677; September 2, 1678; August 19, 1679, when he had attained his colonelcy; and finally on March 19, 1680–81. In a “Brief Account of the Government of Jamaica,” drawn up in 1680, his name appears fourth on the list of justices of the peace for Precinct IV (St. Catherine’s, St. Thomas-in-the-Vale, and St. Dorothy’s), coming after those of Byndloss, Ballard and Long. In 1679 he was one of a committee of fourteen of the Council and Assembly for the Defence of Jamaica, who signed specific recommendations to the governor for strengthening the breastwork, arming the new works, and providing four fire-ships. [Illustration: COLEBECK CASTLE ] On February 17, 1682, the Lords of Trade and Plantations agreed to recommend, and the King approved, Colonel John Colebeck to be of the Council of Jamaica, in the room of Colonel Whitfield deceased, but he had died before the decision reached Jamaica. His will, dated February 20, was proved on March 15, 1682–83. He does not seem to have had relations for whom he cared, for he named none. He left all his estate, real and personal, to his executors, Hender Molesworth and Samuel Bernard (to each of whom he gave £40), to hold for payment of his just debts and legacies. He bequeathed money to purchase a ring to each of Sir Thomas Lynch, Robert Byndloss and Sir Henry Morgan. He left £20 to Henry Howser, the rector of St. Catherine, to preach his funeral sermon. He left £10 each to Dr. Ross and Edmund Duck, the Attorney-General, and £300 to Mrs. Ann Ash; and to every one of “ye Gentlemen of Councill each a ring of 30/- price. To ye church of St. Dorothy’s ye charge of glassing all ye windows and putting in iron barrs.” After his death, the name of Colebeck does not appear in Jamaica history. As his arms are not given on his tombstone, there is nothing to show whether he came of the Bedfordshire or the Lincolnshire branch of the family; but there is a tradition in the Colbeck family that a member of the Lincolnshire branch at Louth was transported to the West Indies for cutting down an elm tree; that he acquired a fortune, and that his estate went into Chancery.
