I've written before about Berkshire County proprietors' (land) records. I recently discovered these have been filmed and are available through LDS, the Mormon Church. In 1920-1921, the county registry of deeds offices compiled the earliest land records for each of the 3 registry districts. A 10-page introduction describes the first land grants and land sales in western Massachusetts for all of present-day Berkshire County, including areas once in Hampden County or in other states (NY, VT or CT). This summary precedes each of the separate district records; then records for each town are listed. The names and locations of these first owners - called (first) proprietors - are traced from the 1730's through 1788 when the county registry system was established. These fist owners had no deeds, and these early transactions (grants, sales, property subdivisions, etc) for the most part do not show in the registry grantor & grantee indexes of land transfers. These colonial records include lists of the proprietors, the acreage and location of each plot, plot plans and notes of subsequent proprietor meetings and later subdivisions and updated plot maps. The degree of detail does vary from town to town. There are every name indexes. The proprietor records have a wealth of both historical and genealogical information.
