John was born 1736 in Wolverhampton, Staffordshire England. John Turnpenny Altree assisted in giving medical treatment on the voyage to NSW aboard the Lady Penrhyn arriving in 1788. Leaving behind his wife Sarah to attend to the their young family.
John soon found himself on Norfolk Island travelling as a member of the first landing party to establish a settlement on the Island, arriving aboard HM Supply in Mar 1788.
23 Apr 1788: I shall send Mr Altree to stay there (Ball Bay) and build a house — I have no doubt but this Valley would produce an immense quantity of Grain as it can be so easily overflowed.
16 May 1788: Two men (sent) off from clearing away on the N.E. side of the hill to assist Mr Altree in removing his things to the plantation where I have ordered him to reside in order to take care of those trees and cultivate the adjoining grounds which may be cleared away in a short time.
22 May 1788: The Sawyer was taken ill and could not do any work sent his assistant out to help Mr Altree in clearing away at the Plantation.
17 Dec 1788: As I find it very necessary to have two or three trusty people settled there I sent three people there with orders to Mr Altree who has the direction of them to employ them building houses for themselves & clearing away Garden Ground. & if possible to get an acre of ground cleared away by the end of May for sowing Wheat. At daylight sent Mr Altree, Thomas Webb and John Anderson (Convict), to Ball Bay to settle there. Sent eight men with them to carry their cloaths, beds, etc at 4pm. 
John left Norfolk Island with the reminding stranded crew of the Late HMS Sirius, aboard HM Supply in Feb 1791, then leaving the left the colony for England from Port Jackson on the Dutch ship the Waaksamheid in Mar 1791 with the majority of the crew of the late HMS Sirius he disembarked on 24 Apr 1792 at Portsmouth.
Governor Phillip to Under Secretary Nepean (Per Dutch snow Waaksamheyd) Sydney 21st March 1791
This will be delivered to you by Mr. John Turnpenny Altree, who came from England in the Lady Penrhyn transport with the First Fleet. During the passage out he assisted in the attendance of such convicts on board the ship as required medical treatment, and has been since that time employed at Norfolk Island by Mr. King, the late commandant, and by the Lieutenant-Governor as an assistant to the surgeon there, and in clearing and cultivating the land, in which line he conducted himself, as far as I am informed, to the satisfaction of those who employed him, until he left the island, for which services he has never received any compensation except twelve pounds, which, since his arrival here, I have directed the Commissary to pay him.
What his future views are he can best explain. He wishes to return and the character given of him by Lieutenant King and Captain Hunter in lines me to wish he may succeed. He will, I presume, be thought to merit some little recompense for the time he was on Norfolk Island, and his demands will not, I believe be very great. He was in the militia as lieutenant and surgeon’s mate, and wished to be received here as a subaltern in the New South Wales Corps…..A. Phillip.
John Turnpenny Altree died 6 May 1798 at St.Peters, Wolverhampton, Staffordshire. The John Altree who died in 1805 St.Peters, Wolverhampton,Staffordshire was his son.
