How long has the oldest gay couple you know of been together?

Just wondering. Me and my baby have been together for 33 years in a 99% monogamous relationship. My first boyfriend in High school has been in his now for 26 years. The oldest couple I know of is a couple of tobacco farmers that have been together for 62 years. They only came out 2 years ago. Before that, everyone in the community thought they were just brothers.
