Should I accompany my spouse to the funeral of someone I've never met?

My husband’s great uncle passed away this week, and until yesterday I wasn’t even aware that he had a great uncle. My husband keeps saying that he doesn’t care one way or another if I go with him.. but I can’t tell if he means that. I should go just to be supportive, right? Or is it odd for me to go to the funeral of someone that I’ve never even heard of, particularly if my husband didn’t seem to be very close to the deceased…?
