Hi Elaine,
These names are not particularly familiar to me, although I have family both from PEI and Kent Co., NB. Well, McDonnell and their connection with the 84th Young Emigrant Highlanders are somewhat familiar as I read a book on the regiment many years ago, and I know they were prominent amongst the Scots in northern New York.
Harpersfield (John and Abigail (Montgomery) Harper, 1768) was in what was then Tyron Co. (now, I believe, Delaware Co.), NY; so I would expect the Harper's to be from that area. However, I believe the Harper's were, for the most part, Patriots.
Robicheau should be Robichaud. The Sweezey's were originally from Salem, MA through Long Island in the 1600's. They are by way of being very distant cousins. A family in Southold, Long Island, NY (probably 1698) were:
Joseph Sweazy
Mary Sweazy
Johanna Seazy
Joseph Sweazy Junjr
Mary Sweazy
Sarah Sweazy
Samuel Sweazy
Richard Sweazy
Stephen Sweazy
Bathia Seazy
John Swazy
Mary Swazy
Jno. Swazy Junjr
Susana. Swazy
Mary Swazy Junjr
Joshua & Phebe Swazy
They would be descended from John (d. 1692) and Katherine (King) Swazey; originally of Salem, probably moved to Long Island with their King and Scudder in-laws due to Quaker sympathies.
Cherry Valley, Ulster Co., NY seems an error, as I understand Cherry Valley was at the north end of the Hudson River, and Ulster Co. (now, I believe, Orange Co.) was at the south end, across from Dutchess, Westchester and (now) Putnam counties.
If the King's Regiment was the King's American Regiment (or perhaps the King's Rangers?), most of the members were from New York and New Jersey. The name, Beers, seems vaguely familiar. Apparently stationed on the Island of St. John 1782 (probably a detached company of the King's Rangers under Lt. Col. Hierlihy's composite command.) However, both Capt. Samuel Hayden and Ensign Joseph Beers were originally of the New Jersey Volunteers. (4th and 5th Battalions), so, again I would question that they were of the '5th Battalion of the King's Rangers'; especially as I do not think the King's Rangers had five battalions; but the NJV definitely did. At:
http://www.royalprovincial.com/military/rhist/njv/njvofficer...is included Throckmorton, who apparently was also on PEI; and:
211. THOMPSON, Cornelius 6th Ensign 3/24/77
3rd Ensign 4/25/78
3rd Adjutant 6/29/80
3rd Lieutenant 2/22/83
212. THOMPSON, John 1st Ensign 12/1/76
1st Lieutenant 8/25/80
213. THOMPSON, Lewis 3rd Ensign 12/19/81
A mention of Joseph Beers at:
http://personal.nbnet.nb.ca/halew/Roll_of_Officers.htmldoes suggest a transfer to the Rangers.
I suspect that possibility that John and Sarah Thompson my have acquired the land from William Harper, but were the first to live on it. Part of the difficulty may be that Kent Co. was originally part of Northumberland Co. An example is the William Harper of York Co. who had a petioned submitted on his behalf in York Co. in 1845 as a soldier of the American Revolution. he was blind, age 87 (b. ca. 1758) and destitute. Suppose, for example, he had served in the war of 1812-14, been granted (as others had) land in Northumberland Co. for his services, never occupied it, but sold it. William Harper had served in the King's American Dragoons, commanded by Col. (Lt. Col.?) Thompson. (1837 petition.) One might think he would think well of the name. William Harper was granted 188 acres (suggesting he was married) in Liverpool Parish, Kent Co., NB 8NOV1828.
I don't know if these ramblings are of any help. Try focusing on one specific couple, and let me know what you have on them. I suspect that it is John and Sarah Thompson who most concerns you, but am uncertain.
Archibald Thompson seems to have settled in what is now Ontario. Apparently on the Niagara Peninsula, in Stamford Twp. A son appears to have m. Amelia McMicking, and I know they were Loyalists in the Niagara area. (again, the McMicking's are vaguely related, and I am acquainted with some of the family and have had occasion to take a brief look at them.) I don't see him connected with Kent Co., NB at all.
