The brig/brigantine Mary sailed from Cork, date unknown, but probably in April. The passengers were all Irish, and their intended destination was the United States, via the port of Boston. The Mary arrived at Boston May 17th 1847, but the passengers were in such a destitute condition, the city authorities would not allow them to land unless the captain was willing to pay a bond for their care. The captain was either unable or unwilling to pay such a bond, so the decision was made to sail for Halifax, Nova Scotia. The passengers protested, but to no avail, and Mary set sail for Halifax May 22nd 1847. A newspaper account from the Boston papers was published in the Saint John, NB, Morning News on Friday, May 28, 1847. On Friday, June 4, 1847, The Christian Messenger (Halifax), reported "Arrived Friday 28th; Brigt Mary, [captain] Wyman, Cork via Boston, 46 passengers who were prohibited from landing at Boston."

Disturbance in the Harbour of Boston.
The British brig Mary, Captain Wyman from Cork, arrived at this port 17th inst., [Monday, May 17th 1847] with forty-six steerage passengers. The city authorities would not suffer them to be landed, owing to their destitute condition, unless the master gave bonds that they would not become a burthen to the city. This he was unable or unwilling to do, and came to the conclusion that he must take them to Halifax, for which port he accordingly cleared on Saturday [May 22nd 1847]. The passengers were naturally much exasperated at the turn matters were taking, and when the pilot ordered the crew to weigh anchor, the passengers took possession at the handspikes and windlass, and assaulted Capt. Wyman, who called to his assistance Capt. Josiah Sturgis, of the revenue cutter Hamilton, who went on board with six men and attempted in his usually judicious and dispassionate manner, to restore order, and directed his men to man the windlass.

The passengers crowded forward, obstructing the operation in various ways, and while Capt S. stood upon the windlass encouraging his men, one of the passengers, who appeared to take the lead, got upon the windlass and collared the gallant captain, attempting to remove him. But Capt Sturgis instantly threw him several feet from him, prostrate upon the deck, and made a signal for a reinforcement from the Hamilton, when another boat's crew, armed with cutlasses, came on board. Capt Sturgis ordered the women and children to go aft, and the men to fall back from the windlass, which they did. He then got the brig under weigh, and accompanied her some distance, leaving her with a fair and fresh breeze.
