The people in that village were so weird that we moved away.
Sounds like you lived in Royston Vasey . . .
Neglecteful parents can impact on the relationships between siblings, too - either bonding them together, or playing off one against another as it suits them. (here I'm actually thinking of a neglectful GP - my paternal GM, who took great delight in causing rifts between family members. She had two mottoes "Whoever has the money holds the reins." and "Divide and Conquer".
She was wealthy (in terms of our family - not JR-M wealthy), and was always promising one person this and another person that a and deliberately spreading lies and discord. I was fortunate as she hated me from my birth (I was the oldest) and treated me like shit. If not, I might have got dragged into the drama, too - as it was, I stood on the sidelines and watched the horror play out.
She destroyed my parents' relationship, as my DF couldn't see any fault in her and took her side EVERY SINGLE TIME, no matter how unreasonable she was. She caused more fights between them accusing my DM of shagging around (she didn't), and as DF (the idiot) was in the Navy, and unable to verify anything, he believed her - after all - his mother wouldn't lie, would she?). He punched my DM from pillar to post sometimes because of this.
After he died, she wanted to move in with my mother (she no longer had my father to run about after her) and was furious when my DM refused to let her. She set my brother and sisters against each other over money -though they all banded together against me in the end - nothing like a common enemy- when she threw a spanner in the works by making me and my husband her executors (!) - we had known nothing about this, but then had to share out assets according to a spiteful and malicious will, and got the blame for it. (We didn't realise at the time that we could have refused - we thought if it was in the will it was a legal requirement - how naive we were.)
Her spite has echoed through the generations.
