This pub, or more technically, pubs, has a complex history I am still uncovering. Although originally called the Prince of Orange when built in about 1733 by James Hickes, sometime in the mid 18th century it became the King of Prussia, although to confuse matters further, the two names are used almost interchangeably from the 1750s to the late 1770s. It is also a well recorded fact that in 1914, for patriotic reasons at the outbreak of the Great War, The King of Prussia was renamed the King George V. Because of this most people consider the Prince of Orange, the King of Prussia and the King George V to be the same pub. HOWEVER, the original Prince of Orange, which became the King of Prussia, was at the building now known as No. 6 Prospect Row, and the current King George V is at 1 Prospect Row, a completely different building. The move seems to have occurred in the mid 1860s (1862 is the last entry for it being at 6 Prospect Row, and it does not appear again until 1867 when it is on the corner of Garden Street & Prospect Row, and it notably absent from sources in 1863 and 1865), with the King of Prussia becoming a private house, and the building on the corner of Prospect Row (a grocer's shop in the 1851 & 61 censuses) opening as the King of Prussia public house. There is an element of confusion here as in the 1841 census the man we know (from directories) to have been the landlord of the King of Prussia is at 6 Prospect Row, as a licensed victualler. However, the corner building (1 Prospect Row) shows a publican living there who can not be traced in any of the directory entries, so the corner building might be an otherwise unidentified pub (or beerhouse) that closed sometime between 1841 & 51 before becoming a shop for a couple of decades, then reverting to a pub.
I do have more detailed information which I will add at a future date.
The Prince of Orange/King of Prussia from c.1733-1862, now 6 Prospect Row is the left hand building. The right hand building (No. 7) was part of the plot the pub was built on, but at that time was probably yards and stables for the pub, not a house. The door on the extreme left is the entrance to No. 5, but the pub had a 'flying freehold over the alleyway beside No.5 fro a height of 8' upwards. Photo taken 2010

At the time of the Inquest the landlord would have been Robert Sowter, who later became the landlord of the Queen's Head for several decades
