how many siblings does Haley James really have?

There's defiently more :) Vivian, another sister of theirs is mentioned. Dunno how many more siblings she has though.

She has an older sister Vivian, then there's Quinn and Taylor. She also has brothers because Karen tells Keith that when Lucas first met Haley, she said that she had a lot of brothers and sisters.

i believe in season 1 haley tell nathen that she is youngest of 5 children.

i think she said she was the youngest of seven in season 1 and nathan mistook taylor for quinn or vivian in season 2

i made this question to like a month a go and no one can tell for sure how maybe siblings she has.I was just amazed let's say when Lydia comes in season 7 and tells something like :'My 3 favorite daughters[...]' and they must have at least 1 more sister(Vivian the one that Nate thought Taylor was in season 2)so i was like 'amazed' when she said favorite daughters cause a parent doesn't have favorite children a parent loves all the children the same but well she has a lot of sibling in season 1 a few times people said so (Karen to Keith , Haley to Nate)

I know it's more than the two sisters we've seen. I forget exactly how many siblings Karen said she had. I do remember Lucas commenting on the reason why Haley spent so much time at his house was because she had to "fight for food" at home. So that has to mean it wasn't just her, Quinn and Taylor. I wish they'd introduce the rest of the James children.

I think she has 3 more sisters(:
Vivian, Quinn and Taylor:D

So there is Vivian,Quinn and Taylor which we knew about and she has another 3 older brothers which are not mention
