Lyn, I finally found the bit about the Greyhound. Luckily I had copied it. It was written by Beverleigh but I'm not sure of the date or which thread it was on. I know it was quite some time ago. Although it includes other information it does mention the Greyhound and the rest is local to the pub so I have left it intact as it may be of interest to other people. Please move it if you feel it would be better somewhere else.
When researching the history of this area, I remember reading that the part of the Hall's Garden centre shop, which fronts Chester Road is what remains of a cottage which was known as Cook's farm. Looking at old maps, I came to the conclusion that Gibbet Hill was behind the New Oscott Tavern, but the old maps are hard to relate to modern ones. I know that Boldmere Lake used to stand where Fosseway Drive is (perhaps a little further covering Lakehouse) and that the Greyhound pub was once a coaching inn used by travellers on the Chester Road, the present building replacing an older timber-framed one. I also remember reading that one of the highwaymen hung on Gibbet Hill was called Jordan and he was buried at the junction of Chester Road and what is now College Road, and the local area was known as Jordan's Grave for a long time after this and his ghost was reported as late as the 1950s. Once reading the Birmingham Gazette from 1799, there was a report of a Mr. Hunt being held up by a highwayman, on the London and Chester Road as he was crossing the Coldfield, who took his pocket watch and money. However, when Mr. Hunt asked for the return of some of his money, the highwayman did so. If I remember correctly, he returned to him five shillings. The Coldfield was well-known for highwaymen.
