Actually, Lydia is already on the vanilla list so you shouldn't have to do anything to make her eligible. As for other NPCs... using addfac 19809 1 only makes them eligible for marriage. It does not make them interested in you. That requires a certain relationship level - meaning they have to actually like you first. Weird, eh? So, as above the next step is setrealtionshiprank player 4 and, for emphasis, follow it up with player.setrelationshiprank player 4. I honestly don't know why the second part is needed, or if it even is, but the first part definitely is. In fact, you can use that on just about any NPC to improve their disposition towards you for any of several reasons - such as turning them into followers, if eligible for that role) Oh, and yes you will need to turn people into followers as well, in which case you want to add addfac 5C84D1 to the mix. Again, merely making them a potential follower is not enough unless they actually like you. See above. Now this will usually be enough to make any NPC eligible for marriage but just in case it does not, the final step (and be sure to Quicksave before you do this in case you screw it up): Click on the NPC and type disable and then enable without leaving the console screen. Emphasis on not leaving the console screen, because once you type disable they will vanish, but their "tag" on the console will still remain. Since they are still tagged, typing enable brings them reappear again. Should you leave the console screen between these two commands, I can not promise that you'll even be able to bring them back. You may, but then again you may not. So don't risk it (hence, Quicksave just in case) and do it all in one pass. What that does is resets the NPC and, in doing so, reloads their dialog options with the new features enabled. Namely, the marriage and/or follower dialog that, for whatever reason, you were not getting before. Using this method I have yet to encounter any NPC that I could not turn into a follower or candidate for marriage. Also, before I finish, I would also like to add this: help _____ 4, with the blank being their name. This will barf up some statistical data on the NPC, including their ID number in the game - which is important when you follow that up with setessential _____ 1 to make sure that they can't be killed. This is how I turned Shal from being just some random Orc chieftan's mistress into one of my personal bodyguards, as seen here: I haven't tried the enable/disable thing yet, because I tried the first two steps on Ondolemar and it didn't work.
