When you meet someone and realize they are the loved one of a deceased person you knew should you tell that person you knew them?

One time I knew a child I worked with (indirectly) died at home. It was a sad affair of course. I had never met the parents formally but saw them at a celebration of his life that we held in the child’s honour.
Years later I met the dad doing business for something else. We were both masked bc of covid so it didn’t hit me immediately who he was (he prob wouldn’t recognize me even without a mask) but he had the same last name as the child I knew. I found later out that he was in fact the dad of the child. I never said anything that I knew his boy. I wasn’t sure if it’s something he would have appreciated. I know when people talk of my mom who’s passed I don’t mind, but maybe a child would be different.
