Unfortunately, in this period, birth records were not kept - only baptismal records. August 8 represents the day of baptism, which may have been a month or two after his birth.

Upon death, Sir George Calvert is succeeded as Baron Baltimore by his son, Cecil Calvert.

June 30 (June 20 Julian Calendar, Wednesday), Britain: Lord Cecil Calvert, second Baron Baltimore, is granted at Greenwich a charter for establishing a proprietary colony on Chesapeake Bay between Pennsylvania and Virginia in the New World by King Charles I of England (it specifies all unsettled lands north of the Potomac River on both sides of the Chesapeake Bay, so as to avoid conflicts with settlers from Virginia Colony; the Lord Proprietor is also to furnish one fifth of any gold or silver in the colony, and provide two arrows a year from local tribesmen to the Royal Castle at Windsor every Easter). Enjoying the rights of a palatinate (descendant rights nearly equal to an independent state, including rights to wage war, collect taxes, and establish a colonial nobility), Lord Baltimore gathers members, mostly Catholic, for the new colony, to be named Maryland after the reigning Queen Consort Henrietta Maria de Bourbon of England (age 23). On the same day, King Charles also issues a proclamation to the Gentry to keep to their residents in the country and not move residence to London, Winchester, or the adjoining towns.

Lord Cecil Calvert, second Baron Baltimore faces his first big challenge at the Royal Court as members of the Virginia Company issue a formal complaint over the creation of the proprietary colony of Maryland by its Lord Proprietor Cecil Calvert, second Baron Baltimore. They claim that the territory occupied by Maryland was not truly unsettled as William Claiborne had a trading station established already on Kent Island in the northern Chesapeake Bay. The Virginians also claim that the charter is written so broad as to violate the liberty of Maryland’s future citizens.

From "The History of Maryland" by John Leeds Bozman (1837):

A petition therefore was framed in the name of the planters, and in May 1633 presented to his majesty, in which they remonstrate: "that some grants have been lately obtained of a great portion of lands and territories of the colony there, being the places of their traffic and so near to their habitations as will give a general disheartening to the planters, if they be divided into several governments and a bar put to that trade that they have long since exercised towards their supportation and relief, under the confidence of his majesty's royal and gracious intentions towards them."

June 14 (June 4 Julian Calendar, Tuesday), the Privy Council of King Charles I of England, still in London during the absence of King Charles during his Scottish coronation tour, addresses the Virginia Company’s petition against the Maryland Grant issued to Lord Cecil Calvert, second Baron Baltimore. The case is deferred three weeks so that all interested parties could be assembled and heard.

July 8 (June 28 Julian Calendar, Friday), Britain: In Edinburgh, the Scottish Parliament, held during the visit of King Charles I of England, Scotland, and Ireland, is adjourned. The King remains in town, and has his agents observe those who dissented from his 32 Acts restoring the Episcopal Church in Scotland. In London, King Charles’ Privy Council hears arguments from both the Virginia Company and Lord Cecil Calvert, second Baron Baltimore, and decides to give both parties five days to work out their differences “in a friendly manner,” and to present any lasting differences to the Privy Council in their next meeting.
