Question:  Sarah Crocker Conway leased a theater in which at least 278 individuals were killed on what date?

 The conflagration killed at least 278 individuals, with some accounts reporting more than 300 dead.  One hundred and three unidentified victims were interred in a common grave at Green-Wood Cemetery. The Brooklyn Theatre Fire was a catastrophic theatre fire that broke out on the evening of December 5, 1876, in the then-city of Brooklyn (now a borough of New York City).

More than two dozen identified victims were interred individually in separate sections at the Cemetery of the Evergreens in Brooklyn. <SEP> Sally Fox is a passenger-only ferry built for the King County Water Taxi.  The "Sally Fox" is 104 ft long and has a capacity of 278 passengers seated in two indoor decks and outdoor balconies.  The aluminum catamaran was built in 2014 by All American Marine in Bellingham, Washington for $6.25 million, and is used primarily on the Seattle–Vashon Island route.  The boat began operating on the Vashon route in April 2015, replacing two leased boats.  The vessel was named for Sally Fox, a Vashon Island activist who fought for passenger ferry service to the island.  It is the sister ship of the  , which entered service in 2016. <SEP> Sarah Crocker Conway (b. Ridgefield, Connecticut, 1834; d. Brooklyn, New York, April 28, 1875) was an actress.  She was a sister of Elizabeth Crocker Bowers, also an actress.  She made her debut in Baltimore, Maryland in 1849, playing Parthenia and other leading parts.  In May 1852, she married the actor Frederick B. Conway, and the two thenceforward acted together.  In 1859, they opened Pike's Opera House in Cincinnati, Ohio with a first-class company, but the engagement was not profitable, and they returned to the east.  In 1861, they visited England, and filled a short engagement at Sadler's Wells Theatre, London.  After their return, they became star actors, and made an extensive and profitable tour.  In 1864 Sarah leased the Park Theatre in Brooklyn, and subsequently the new Brooklyn Theatre, in which for nine years her husband played leading parts.  Sarah Conway possessed a tall and graceful figure and an expressive countenance, and was a versatile actress and a popular theatre manager. <SEP> After a successful career as a Queensland and then Australian international representative, in the 1954 pre-season Crocker signed a then record one-season deal for an Australian to move south and play for Sydney club Parramatta in order to assist his family who had lost their home in a fire the previous year.  Parramatta finished the 1954 NSWRFL season with the wooden spoon however.  In the post season Crocker was selected for the Australian national team's campaign for the 1954 Rugby League World Cup tournament, the first ever, which was held in France.  Crocker didn't play in the Kangaroos' first match which was lost to Great Britain, but was selected as a second-row forward for the second match against New Zealand which Australia won.  He played in the third match against France which the Australians lost, meaning they would fail to reach the final.  He is listed on the Australian Players Register as Kangaroo No. 278.  The following season was Crocker's last in the NSWRFL Premiership's first grade.
