If you are of the pure-blood PC gaming master race, you can remedy your problem with an easy solution: the console!
Just hit the tilde key (`/~) and type in moveto <actor ID>, where the actor ID refers to their RefID. The RefID for Rayya is xx005216. The two xx's are actually numbers, but given as xx's because a person's load order of Skyrim expansions may be different. For vanilla Skyrim you replace the xx's with two zeroes, where Dawnguard could be 02, and Dragonborn 03. Jordis the Sword-Maiden's RefID is 000A2C95.
If you don't play on the PC, kill someone and get thrown in prison. Maybe the missing people could spawn outside the jail you're in.
