WIBTA for asking about my friends ashes?

On Christmas Day 2024 my (29 M) best friend (30 M) was found to have passed away in his sleep. I did not know his family well as I'd only met them a couple times. Adult friendships are like that. They had a blood relative only gathering for his funeral. I have his families contact information still and I used it once because I found out I was in possession of a sensitive item that I believed they would want back. I mailed it to them. I tried coming up with ways to memorialize him in my own. Honestly I wish I had some of his ashes. I know it's been well over a year. I am worried about asking about his ashes, physical memorial sites, or having any keepsakes especially since it's been over a year. It could bring their grief back to the surface.

Tell me, would I be the drama for reaching out to his family about this stuff?
