My father left me and my mum when i was 6 months old and died when i was 9 years old. It had ZERO affect on me until i have in high school when i started to have a bad relationship with my mum and imagined that if my dad was still alive he would come rescue me buy me stuff i wanted etc etc. I dont think she needs personal closure but she may want memories for later on. You can take her but don't make a big deal of it. She might feel a little uncomfortable around people crying and carrying on around her so please protect her from that. People may try to connect with the dead man by trying to hug her and all that BS that comes with being his flesh and blood. Happy to chat more if you want to inbox me.
