Items from Divorce

So, I got divorced 3 years ago. My wife and I just listed our house for sale and I got an email from my ex requesting a few “heirlooms” that she saw in the photos. There were small things and some things in the basement in storage.

In the settlement, it mentions all family heirlooms go to each person under the personal property section. There is a clarifying statement saying that we must within 30 days arrange a time to give my ex her possessions from the house. We did all of that. My question is two fold: is there a legal definition of heirloom (is something from a parents work an heirloom?) and do I still need to comply with the request 3 years later even those she just didn’t take her items not like I hid them or anything?

Thanks for your help!
