Times Are Changing (1) - S9-E1
Character mistake: Almanzo says he hasn't seen his brother Royal in 10 years, but in fact he saw him not long ago as he looked after his 2 sons who were terrors, and at that time Royal didn't even have a daughter.
Suggested correction: Royal's wife was pregnant when he visited years before Laura had the baby.
What happened to Pearly Day? Almonzo's younger brother?
Not sure if this varied in the show, but in real life Pearly Day had six children and died in 1934 just a month prior to his 65th birthday.
Almanzo had 2 brothers. Royal and Jenny's dad, the one that was dying.
That may not work, unless Laura and Almonzo were not married yet at the time of Royal's first visit, but it is a good suggestion.
In the TV series, the episode that they were taking care of the boys was only six episodes before Laura found out she was pregnant, and Nellie's babies were still babies throughout that time so it wasn't that long. And Rose wasn't that big When they came to visit, so it was probably only 1 1/2-2 years of a time gap. Also, when Royal and Jenny came to visit, Almanzo introduced Royal to Laura as if they had never met before.
It was NOT years! Royal, his wife and 2 sons visited Almanzo in Season 7. His wife did announce she was pregnant in the end. However, when Royal comes back to visit with Jenny, at the beginning of Season 9. If Jenny is supposed to be the baby Royal's wife was pregnant with then she would have still been a year old or 2 at most. They do explain that his wife died, but what about those boys? They would have been early teens by then. Nothing is ever said about them or why they aren't with Royal.
But Laura says "glad to finally meet you Royal", when he came with Jenny. But she met him when he came with the boys.
Welcome To Olesonville - S9-E3
Continuity mistake: Mrs Olsen cleans up the old Hansen house to sell, however it was made the blind school years back and burned down, killing Mary's baby and Alice Garvey.
Revealing mistake: When Laura picks up Baby Rose from Thomas Stark, the blanket is flipped up and you can see a plastic doll's leg, then when she goes into the bedroom, she has the real baby.
Visible crew/equipment: As the train is pulling up you can see a car in the reflection in the train window and a man wearing a yellow shirt. Possibly a director or Michael Landon.
Home Again - S9-E16
Character mistake: Mrs. Oleson, talking to Willie, tells "Albert" to go clean up his room while Mr. and Mrs. Oleson, Willie, and Albert are talking in the Mercantile. (00:39:20)
Suggested correction: Mrs. Oleson isn't calling her son 'Albert'. She is talking to Albert as he's leaving the store and says "Well, it's nice to have you back, Albert" then she turns and looks at Willie and tells him to clean up his room. There is a slight pause between "it's nice to have you back" and "Albert" but she is not looking at Willie when she says Albert's name.
Factual error: This episode was mentioned by Laura at the beginning as taking place in December 1889. Rose was born in December 1886, so she should be 3 years old now, but she is shown through the episode appearing only to be roughly 6 to 12 months old and still in a crib.
Times Are Changing (2) - S9-E2
Factual error: This episode takes place around 1886/1887 and in the episode Royal dies. In real life, Royal didn't die until 1925.
