Bon soir to you, thank you (I need this week to be amazing bc it’s my first 5-day week at work in awhile, bc of the holidays and the snow day last week, omg it’s gonna be rough, lol), I’m very well! Hope you are, too, and that 2018 is treating you well, so far. I’m stretching my creative muscles again, making promises to ppl about fanworks I have in the pipeline that are ACTUALLY GOING TO HAPPEN. Yissss. 2018 is going to be a more productive year ^_______^
(No worries re: the spam of questions, I’m going to treat them as one mushed-together question, hope that’s ok with you!)
Louis having a living lineage and
being a patron to it is entirely possible! Do I personally headcanon that he does, definitively? That’s hard to say… I could go either way on it. I can parallel-headcanon, and have it both ways 😉 It depends on the fanfic/fanart/etc. I’m consuming, whether I headcanon yes/no on that.

A) On the one hand, I think he’d be charmed by seeing his own mannerisms (or that of his immediate family!) in his descendants, as can happen. ❤
I know I’ve seen at least one fic that had Louis discover a great-great-great….(idk how many?)…grand-niece in NOLA, and even being just a child, she resembled Louis physically and/or psychologically, and he was deeply touched about that *u* I don’t remember whether he became a secret patron to her… I think the fic was by @gairid/ @vampchronfic, if that ficwriter sees this post, they are invited to reblog/comment the name of the fic! It was sweet without being pure fluff.
B) On the other hand, I think Louis might take some comfort in the fact that he no longer has a family to support financially or emotionally, and no family to worry about from a distance,
…which Maharet has made a career of doing with her own family bc she enjoys it. Louis is fiercely devoted to and protective of those he loves, and he chooses those loved ones very selectively. Canonically (post-IWTV), he has few ties to the other vampires in the coven, and no mortal ties other than Merrick, but she bewitched him, and admitted to doing so, so I don’t think that she really counts. If we include PL/ROA, then one could argue he has an attachment to some of the mortals in those books, including Rose.
Another thing that’s come up in canon now and then is the idea that mortal relatives/descendants can be used to try to blackmail the vampires; mortals can be taken hostage and threatened with violence unless ransom of some kind is paid for them, as happened in PL. So I think Louis would be relieved that he wasn’t unintentionally placing any innocent mortals in harm’s way simply for being related to him.
^^^ALL THAT SAID, we could always use fresh fanart/fanfic/etc., especially on this kind of rarer topic, so anyone who sees this post is invited to share their headcanons on it, too 😉
Hit the jump for just a little bit more.
Canonically, Louis tells us that his sister married, and yes, he did give her money to invest for the family:
“My sister was married in my absence, for example, while I had a `malarial
chill,‘…With dozens of miserable headaches I would receive my sister in a darkened bedroom, the covers up to my chin, bid her and her husband
bear with the dim light on account of the pain in my eyes, as I entrusted to them large amounts of money to invest for us all. Fortunately her husband was an idiot; a harmless one, but an idiot, the product of four generations of marriages between first cousins.” (IWTV)
I skimmed IWTV and I didn’t see any mention of his sister having any children.
I don’t know why AR included that the husband was the result of an incestuous lineage, that may have been normal at the time? I don’t know what impact AR intended that information to have on the story. Maybe just that the husband never questioned Louis’ strange behavior re: meetings in his darkened bedroom bc he was, as Louis said, “an idiot”? Maybe this was a little reminder of Louis’s ego, that he felt he was a better man than his sister’s husband?
BTW, Louis’s sister has a fanon name, some fans have accepted it as fanon anyway, Henriette.
Personally, I do headcanon that Louis has at least a few mortal friends in NOLA and San Francisco, like a particular barista at a coffee shop he haunts in the French Quarter, and a few other locals who have done work at Rue Royale over the years. @gairid/ @vampchronfic also has an OC, Brian Callahan, who I think Louis cares very deeply about ❤
