This is going to sound a little creepy, but you should also bring a camera to family funerals (specifically the gathering that takes place afterward).
At least in my family, funerals are pretty much the only time we all see each other anymore (we're scattered all over the country), and our tradition is a large meal after the ceremony where we all get together and reminisce about the departed. Some of the photos I've taken at the last couple of gatherings are the last photos ever taken of a few of my other relatives, and everyone was glad to receive them afterward.
Ask the immediate family if it is OK, and if they're OK with it, take as many photos as you can of everyone. We're all going sooner or later, and you just never know when.
