I will create separate entries of The Walton as there are different room constellations, different locations and non-Waltons room. This pic showing Jim-Bob (on right) and Elizabeth sharing one room in s1e2. John-Boy just leaving the room. (Haven’t checked season 2 yet). I remember Jim-Bob sharing a room with Ben and Jason in later seasons. Also John-Boy, Mary-Ellen and Erin are not at the Walton’s home for some time.
I also have uploaded a good pic of John-Boy’s room. More infos at the main entry which will later be a series overview post. More to come soon.
