While a resident of Schenectady NY, he enlisted 8 Dec 1781 in the King's Royal Regiment, 2nd Battalion. He was 5'-5" tall. He fled to the Kingston area and lived with the Indians until the end of the war. However, in 1784 he returned to the states for his family.
During 1785 he returned to Upper Canada. On 2 Sep 1785 he received a grant of 200 ac, L2, C3, in Twp No. 1 [Cataraqui, now Kingston Twp). Sometime later he exchanged this lot with Terrence Dunn and David Purdy, who were the listed owners in 1789/90. Then, on 26 Nov 1800, a Fiat was issued in his name for this same property, and it was registered to him on 4th Aug 1802.
Also, during 1785, he was granted L10, C4, Twp. No. 3, [Fredricksburgh], Midland Dist, UC. However, he apparently did not live there for very long, if at all, although he retained title. [See petition of Thomas Wager, Ontario Archives RG1 - A II - 5, Heir & Devisee Records, which is also transcribed here. Thomas Wager's daughter Elizabeth married Francis Powley, Jacob's son.] "2 May 1803, -- No. 4 -- Thomas Wager of the Township of Fredricksburgh in Midland District, yeoman, claims the E˝ L10, C4, of Fredricksburgh, originally drawn by himself, a soldier in the late Royal Yorkers. -- [Petition allowed] -- Claimant was placed on the lot by McKay, the principal officer of the settlement, upon the relinquishment of Jacob Powley, who first drew it and is on the map. And Wager has lived on the lot 18 years [since 1785] to the knowledge of the members of the board. -- [Petition allowed]." The lot was registered to Thomas Wager in 1803.
Jacob Powley's name appears on the 1786 Provision List: boys over 10-1, boys under 10-2, girls over 10-1, girls under 10-1. This indicates that the family was not yet self-sufficient, a hardship suffered by many other early inhabitants.
On the 22nd Oct 1787 he received a grant of 200 ac, L9, C6, Twp. No. 1 [Cataraqui], a property which he held until a Fiat was issued on 26 Nov 1800, and was registered in his name 4 Aug 1802. On the same day, his father Francis drew L10, C7, Twp. No. 1. It is assumed that father and son lived on these adjacent lots.
Also on the 22 Oct 1787 he received a grant of 200 ac, L13, C6, Twp. No 1 [Cataraqui]. He held this property until it was registered in his name on 10 Mar 1806. Later the same year, 13th October 1806 he sold it to Samuel Purdy. On the deed of bargain and sale he signed his name "Johann Jacob Pauli".
On 10 Aug 1801 he obtained a patent, (registered 5 Nov 1801) to 200 ac, L22, C4, Kingston Twp. This property was owned in 1789/90, by Capt. Grass and Lt. Ellerbeck. In 1996 this property was owned by the Little Cataraqui Creek Conservation Authority.
On the 16 Sep 1802, Jacob came into possession of 200 ac, L10, C7, a property previously owned by his father Francis Powley Sr. who had received it as a grant on 22 Oct 1787. [See petition of Jacob Powley, Ontario Archives RG1 - A II - 5, Heir & Devisee Records, transcribed here.] "16 Sep 1802 -- No. 1 -- Jacob Powley of the Township of Kingston, yeoman, claims L10 in the 7th Concession of the Township of Kingston in the Midland District, originally drawn by Francis Powley, a UE. -- [Petition allowed.]"
On 23 Nov 1803, land petitions by his children Francis, William, Jacob, and Hannah were received by the Land Board, and were read 28 Nov 1803. It was then that Jacob learned that his name had been struck off the UE List, (John Collins had indicated he was a member of the German troops, not the British Troops). A subsequent petition to have his name reinserted on the list, was approved 28 Feb 1805. His family re-petitioned, and received their lands in 1807, and afterward.
His gravestone reads: "Here Lays The Body Of/Jacob Powley/Who Gave Much/Satisfaction Until/The Last Period When He/Sat In His Chair Facing The/Door On The 21st Day of June/2 o'clock Afternoon Year 1814/He Lay Down His Head With/Out A Struggle Or a Groan/To Sleep In Silence Being/Aged 69Yrs 8M 7Dys." The grave is located only a few feet south of the southwest corner of the Methodist Church at Cataraqui, Frontenac Co, ON, CAN.
Census records show the family origin as "German".
