Michael Learned (mother Olivia Walton) and Robert Thomas (oldest son John-Boy) were unable to attend as they are both appearing in stage shows.
Ralph Waite (father John Walton) was there with all of his other TV children. Earl Hamner, Jr., creator of the show, was also at the reunion.
Mr. Hamner said at the reunion, "The series succeeded because the climate was right then. There was a yearning for stability and unity."
The show has been off the air for 31 years but still has a very large following of people that watched it back then as well as younger people that are seeing it now in syndication for the first time.
