Notes for Lt. Col. Ebenezer Jessup
[BBB]: From a New England family. A King's Loyalist soldier from New England (who lost his property as a result). Apparently his son married into the Bowes-Lyon family (whoever they are) and thus has some sort of link with the Queen Mother. Well, the ex Queen Mother now. I don’t know what this link is.
According to [JB] 
he received an official appointment in Calcutta, India, and went there in 1790.
From [JB] 
comes this statement from Leah Jessup, dated 8 July, 1838:
In answer to your enquiries about my father, Lieut.-Colonel Ebenezer Jessup’s property, I can state to you that it was in the Province of New York in America, and a part of it was in and near Albany; but the whole was lost by his taking part in favor of the British Government.
My father raised a regiment at his own expense, and went with it to Canada, and commanded it during the whole of the American war. He was in the campaign with General Burgoyne, and was taken prisoner with hi sarmy, after which he returned to Canada with his regiment, and upon the Americas breaking their treaty, he served again actively during the remainder of the war. On his first quitting Albany to go to Canada, my father buried all the deeds and papers which regarded his estates, to secure them against the plunder of the Americans, hoping to return in time to save them from being spoiled; but the war having taken an adverse turn, he was so long absent that upon their being opened they were illegible, and from this circumstance he wanted proof of much of his claims against the Government for his lost property. The American Congress were so exasperated against him for the part he took in favor of the British Government, that they outlawed his person and confiscated his property, which they valued at £150,000 when they put it up for sale. My father received a very trifling compensation for all this great property (I think only about £2,000), nor did the Government pay him for the expense of raising the regiment, which I have heard him say cost him about £2,000.
At the conclusion of the war my father’s regiment (The King’s Loyal Americans) were put on half-pay, and as a compensation for services had lands allotted them in Upper Canada. My father’s portion was Lieut.-Colonel Commandant was a thousand acres, and was located somewhere near Yorktown (now Toronto); but from my father not choosing to settle there with his family, and from neglecting to cultivate it, this property was not secured to him. All this I state from memory only.
Ebenezer also appears in the Canadian Dictionary of National Biography. 
The relevant bits say:
About 1764 Edward and his brother Ebenezer moved to Albany. There they formed a partnership, and over the next decade the two engaged in land speculation on a grand scale in the upper Hudson and Lake George areas. In their speculations they were no doubt aided by their close relationship with Sir William Johnson and John Butler. The brothers eventually established a community , with mills and a ferry, about ten miles above Glen Falls on the Hudson. This settlement, which became known as Jessup’s Landing, was a focus of loyalism in the years just before the revolution, and when Sir Guy Garleton succeeded in driving the American forces out of the province of Quebec in the summer of 1776 the Jessups led a party of some 80 loyalists to join him at Crown Point (NY).
The Jessup party was first attached to Sir John Johnson’s King’s Royal Regiment of New York, but on 7 June 1777 the King’s Loyal Americans corps was tentatively established with Ebenezer as lieutenant-colonel and Edward as captain. Although the corps was not fully formed, the Jessup brothers took part in John Burgoyne’s campaign, with Edward as commander of the bateaux service on the Hudson. Both Edward and Ebenezer were taken prisoner in the Saratoga campaign but were paroled and allowed to make their way to Quebec.
Since many members of the King’s Loyal Americans were dispersed during the Burgoyne fiasco, the unit never attained its established strength and remained for the next four years a semi-independent appendage of Johnson’s regiment, engaged mainly in building, repairing, and garrisoning fortifications around Montreal, Sorel and lower Lake Champlain, although it also took part in several raids into New York. Edward went on such raids in October 1780 and again the following fall. It was probably these services, as well as his administrative capacities, that led Governor Haldimand to choose Edward over Ebenezer as major commandant of the new corps of Loyal Rangers, created 12 Nov. 1781, from a number of smaller military formations including the Loyal Americans. The new corps soon became known as Jessup’s Rangers.
From “The History of New York State”, Book IV, Chapter I, Editor, Dr. James Sullivan:
----------The most important historical incident of the colonial period was the "Tolton and Crossfield Purchase: since this covered the greater part of the county. This was really the Jessup purchase, as the two whose names are connected with it, and are placed on most of the deeds since issued, were dummies for Edward and Ebenezer Jessup. Before the ending of the Revolution came an interest in the "unknown north." The Jessup brothers had great influence with Sir William Johnson, Governor Dunmore and General Tryon. They wanted to buy all the land they could get above Albany. Having already made application for 40,000 acres, it was thought best to buy indirectly in the matter of purchasing some 1,115,000 more acres of the mountains section.
On June 7, 1771, to their agents, Tolton and Crossfield, was sold this great tract, and in the next year the Indians met in solemn conclave and also conveyed the land. For this the tribes received about three pence an acre, or a total of £1,35. Theoretically, the land was sold, but before being sealed and the bargain concluded, some $40,000 had to be turned over to King George III. Most of the modern conveyances of land are traced back to this original grant.
What a couple of bloody crooks those two brothers must have been! There are records all over the internet of their land purchases.
There is an enormous amount of information about Ebenezer in [JB]
