Series I. Commonwealth v. Bakerstown Proprietors contains the pleadings, petitions, and judicial decisions related to the case, depositions gathered as evidence to be used by the litigants, miscellaneous court papers from other cases involving Bakerstown land, and some of the records of the Bridgham Proprietors, the true claimants in Commonwealth v. Bakerstown. Commonwealth v. Bakerstown Proprietors arose from a competing claim for the Bakerstown grant, brought by the Commonwealth on behalf of John Bridgham. Although litigation did not formally start until 1790, there are some documents included of earlier date, which were presented in the course of the litigation. As the years passed without a final determination of Commonwealth v. Bakerstown Proprietors, reviews and summaries proliferated, as new judges and commissions had to be brought up to date.
