The largest "thistle brooch" was discovered in 1785 and another in 1830, with the bulk of items being recovered in two groups close to each other by archaeologists in 1989.
[1] Whether all the finds made close to each other were originally deposited at the same time remains uncertain, but it is thought likely that at least the brooches were.
Later archaeological investigations in 1989 at the same spot revealed other silver items which confirmed this was a dispersed hoard and not a solitary loss of one brooch.
