The parents of the virgin Mary. Their names come down in tradition; it is not their names that are important but who they are.  Jesus had a mother, so he must have had Grandparents, who would probably have brought his mother up to be the person she was, and who may or may not have been their for Jesus as well.  And the same for St Joseph’s parents, who I’ve not heard mentioned, but could also be remembered today.

Hooray for: Grandparents
Song: Grandma (or whatever) we love you.
