We have several patterns named "Brighton", none being your pattern. The Database emphasizes the 19th century, so I am not surprised that we do not have your pattern recorded. The Database editor will see your post and it is up to them to decide if they want to add your version. I have no idea as to how common your pattern is. I would think your best bet to find more would be to regularly troll eBay and the various sites such as Etsy in search of the pattern being offered. Good luck!
