The only one who remembers

Both my parents died 30+ years ago and my Aunt who was the last of her generation died last May. My oldest brother died 5 years ago. I have a half-brother who is more or less the family ne'r-do-well still living but we have not been in touch for many years. I have the oddest feeling of wanting to see him only because he is the only one who remembers the old days, who remembers the people and the houses and the times. I don't suppose I will but it is so odd to know that no one remembers. Has anyone else experienced this?
