Meanwhile, the number of those in England interested in the venture continued to grow, and a royal charter, under the broad seal, was granted March 4, 1629, in the names of Sir Henry Rosewell, Sir John Younge, Thomas Southcott, John Humphrey, John Endicott, and their associates, the total membership of the company being about one hundred and ten.[291] The grant followed somewhat closely that received by the Virginia Company in 1609, the patentees being joint proprietors of the plantation, with rights of ownership and government similar to those enjoyed by the earlier London Company. A General Court, to meet quarterly, was provided for, and annually, at the Easter session, this court was to elect a governor, deputy governor and a board of assistants, consisting of eighteen members. By an important clause, six of the latter, together with the governor or his deputy, constituted a quorum, and were therefore required to be present at the sittings of the court. The General Court, consisting of the members of the Company, known as freemen, was also given the power to add to its number, and to make such necessary laws and ordinances as should not be repugnant to the laws of England. The first governor was Mathew Cradock, with Thomas Goffe as deputy, the Assistants including Sir Richard Saltonstall, Isaac Johnson, John Humphrey, John Endicott, Increase Nowell, Theophilus Eaton, and John Browne. It was this charter of a proprietary company, skillfully interpreted to fit the needs of the case, and constantly violated as to its terms, which formed the basis of the commonwealth government of Massachusetts for over half a century.
