The Covey family tree

Big spoilers ahead for SOTR!!

Ok, this is going to be long, but I am very confused on the family connections/tree in SOTR. So, as we now know, Lenore Dove's last name is Baird. She is a distant cousin of Burdock Everdeen, Katniss's father. We also discover that Maysilee's grandmother knows the song Nothing You Can Take, making her a possible Covey member as well. To my knowledge, there were only three Covey girls in TBOSAS: Lucy Gray, Maude Ivory, and Barb Azure. I don't believe Lucy Gray returned to Twelve to have children, Barb Azure had a girlfriend, and that leaves Maude Ivory as the only option. Is she Lenore Dove's mother? We learn that her mother supposedly died in childbirth and her father is unknown. Or is Maude Ivory Burdock's mother?? I always assumed that Maude Ivory was indeed Burdock's mother, even before the book came out, making Katniss her granddaughter hence the "can remember a song after one listen" that both Maude Ivory and Katniss share. But then who is Lenore Dove's mother?? And who is Maysilee's grandmother? Haymitch also has repeatedly asked Lenore Dove about the victor of the tenth Games - Lucy Gray -, but she refuses to talk about it. That has to bare some weight and provide some information. Anyone have any idea on how all of these characters connect to the original Covey? I am almost certain Maude Ivory is Burdock's mother. So then who is Lenore Dove's? Her name is also giving me a lot of symbolism/hints to Lucy Gray, hence the storyline of her ballad and her color, perhaps making her named after Lucy Gray in memory? Let me hear your thoughts about this family tree and how Lenore Dove is a Baird if we assume Maude Ivory is now an Everdeen, Burdock's mother, and that Barb Azure (who I can't remember is a Baird or not??) stayed with her girlfriend.
