Photographers who photograph their own relationships

I’m looking to come up with a list (not necessarily exhaustive, but at least a jumping-off point) of photographers who, in their work, explore their own relationship to another person (or people). So, to clarify, not photographers who focus on other people’s relationships to one another, but photographers who focus on their own relationships. Relationship doesn’t necessarily mean “romantic”; it may be a familial relationship or some other type. The key is that the photographer is an active participant in the relationship. The photographer may or may not be in the photographs.

I have some in mind, but I’d like to open this up as a blank slate. Have at it. And thanks!
