As for rifles from the New England and New York areas my information is somewhat limited.
The book KENTUCKY RIFLES & PISTOLS 1750-1850 (GOLDEN AGE ARMS COMPANY. COPYRIGHT BY THE KENTUCKY RIFLE ASSOCIATION) shows a few on pages 165-170. Bear in mind that the origin of the guns in some cases is speculative.
pg 165 has a Rhode Island Flintlock dated 1776 with a "Octagon straight barrel .45 inches long, .45 cal. rifled. Butt plate 1 3/4 inches (wide). Uncarved walnut stock. "G Westcot" (1736-1812) along with a date inlaid with silver wire on cheek side of butt plate."
The stock shape is similar to a Buck County in that it has a curved bottom and a very slight roman nose comb. The patchbox is similar to a Lancaster Daisy style and the sideplate is anything but a rectangular shape.
pg 166 shows a Flintlock "New England gun signed H. Llocomb Worchester, Massachusetts. Length 59 inches. Octagonal-straight barrel 43 inches long. .59 cal. rifled. Butt plate 1 5/8 inches. Uncarved cherry stock..."
The stocks butt is fairly straight, similar to a Lancaster but with more drop. The patchbox is a daisy style. The sideplates consist of two pieces, the upper, aft one being a modified ellipse and the forward one a curved acanthus leaf shape.
Page 167 shows a Flintlock "New England. Signed H. Pratt. Ca. 1832-1861. Roxbury, Massachusetts. Length 50 1/4 inches. Octagonal barrel 34 1/2 inches long. .58 cal. rifled. Butt plate 2 inches. Uncarved walnut stock with 7 silver inlays and wire decoration."
Patchbox finale is a pineapple shape. Upper aft sideplate is a ellipse. Forward screw does not look like it is sitting on a plate.
Stock shape very much like a Lancaster but with a very sharp drop at the front of the comb.
page 168 shows 5 New England rifles. They all seem to have the straight comb of the Lancaster style butts.
Two of the rifles are Flintlocks. The calibers mentioned are .45, .51, .52 and .58.
Three have Cherry stocks while two have walnut.
Barrel lengths are from 36 to40 3/4 inches
Two Patchboxe fineals are Pineapples and three are
what I would call "horseheads". The off side of these guns are not shown so I don't know about the sideplates.
Page 170 shows a very ornate backaction percussion gun. I would guess it to be from the 1840-1855 era. The stock comb is rather straight like a Lancaster, the trigger guard is very unusual.
After looking at these guns I would say you would be fairly safe in going with a older Lancaster style precarve (if your planning on starting with a precarved stock), in Cherry. A .50 caliber 42 inch barrel would be about right.
As this sounds like it is your first venture into gunbuilding, I would suggest keeping the patchbox fairly simple like Track of the Wolf's #PB-Kit-1 (daisy) or # PB-Kit-4 (Horse head).
You really need to buy the Track of the Wolf catalog. They don't cost much and the photos are full size. The catalog will also give you a good idea of what parts are available.
I would also strongly suggest that you consider buying a copy of the above mentioned book. There are hundreds of photos of many fine old rifles and a reference like this will be a interesting addition to your collection of books.
