Bereavement and NC family members

[PearWhere]

I recently lost my mum who was NC with her entire family. Probably since the late 90s.
As I was a child I don't know why so can't give any more details there.
After looking through social media I have found her sister
I am wondering if I should let her know what has happened or if that's a bad idea? Has anyone been through similar?

Similar-ish. My mum had cancer and as she was dying she apparently asked that we didn’t tell her NC family (only a much older brother and his one adult DC), but once she did die my dad rang him and they all came to the funeral. I did try to forge a relationship with my cousin but that didn’t last (don’t really know why but they slowly stopped replying!) so I do believe my mum was right bless her. I never knew the full story as to why they were NC but I think it was to do with jewellery my mum was given when her mum passed, but it was never mentioned directly to me. (My dad gave them some jewellery when they came to the funeral which looking back was really weird so maybe that’s why they came?)
It’s up to you if you think you or they would benefit from knowing about her passing but me personally I wouldn’t have contacted my mums NC family as I feel there was no benefit and felt like mum was a bit betrayed.
I’m sorry for your loss OP.

I think you should respect your mothers choices and leave it.

Assume she had her reasons.

I am nc with my Mother and have told dh that if I die before her, he mustn't let he come to my funeral or have any contact with our kids.

I would rather go straight for cremation with no service than risk having her there.

Family is only family when there's love.

I am really sorry for your recent loss.

I would focus on processing your own grief now - it’s what you Mum would have wanted.

A quarter of a century with no contact says it all from both sides.

You may get rejected or ignored and that would sting badly at a time when you are especially raw.

It's something your Mum and her sister actively chose not to resolve in life - it was between them.

I’ve been through similar, don’t do it. No good comes of it and they suddenly rewrite history.

That’s very likely. People with axes to grind could cause you deep emotional harm at this raw time in your life.

I think your mum had her reasons, if she wasn't the type to fall out with everyone, then she had a specific reason for rejecting these people.

You are raw right now, and seeking solutions. They may take advantage of you. Be careful.
