This is family...not some dude you've never met. He paid you, your cost to make the album is 'sunk'. You wouldn't have charged them then, as it was included. The length of time is irrelevant to the discussion. Is this the hill you want to die on with a family member? I would provide w/out question and in all likely hood make a family joke about it or something. The fact that you are even asking is a bit unseemly. The only caveat to this is that the album should be of the same/reasonably the same as you would have offered 5 years ago. If they are demanding the gold bound edition printed on paper farted out the butt of a unicorn...then charge accordingly.
