The New York Probate collection is arranged by county. Under Dutchess County we find a very long list of links to a series titled "Ancient Documents." Although nested under the New York Probate collection, it appears that few of these files have to do with probate issues, but instead have to do with other court and legal matters. Scroll down through the list of links and you will find General Indexes to at least part of this collection. Here is the index page on which the files (nos. 1681 and 1682) for Matheus/Mathew Brewer appear.

The location, "Sweago" named in Dr. Sackett's bill, also is of interest. I believe it can only be a phonetic spelling for Oswego, which is located on the eastern shore of Lake Ontario in present day Oswego County, New York. According to the History of Oswego, New York (Philadelphia: L. H. Everts & Co., 1877), pages 19-24, the area saw English and Dutch traders by 1700. In 1721 or 1722, Fort Oswego, a trading post was established and a fort was built in 1727. Travel between Oswego and the greater New York City area (including Dutchess and Westchester Counties) would not have been easy or quick, although a good portion of it would have involved water travel on the Hudson River and it's largest tributary, the Mohawk River.
Prior to finding this file we were certainly aware of the fact that some English and Dutch colonists from the areas of New York where towns were well established, had interests in and made travels to some of the more outlying areas of their known world such as the trading post at Oswego. This file, however, is the first evidence I've found that specifically points to a member of one of the early colonial Brouwer famlies being involved in such an enterprise.
We also can only guess at exactly what ailment afflicted Mathew Brewer to the point that Dr. Sackett had to make a house call. His bill describes "drinks" and "engreediences" (ingredients) that were apparently used to induce vomiting and "purging," which evidently were method believed effective to cure Mathew Brewer of whatever condition it was he had. (Perhaps it was something affecting his gastrointestinal system). In any event, Mathew Brewer apparently recovered, and in 1743 was healthy enough to be sued by Dr. John Sackett. It also looks as if Mathew hired a man named John Alsop, as his attorney.
