I would think that if they were farmers, they would be keen to keep the land in the family.
I've been looking at some of the family trees posted around the internet for this family.
A major mistake of several of them, is that they claim that Elizabeth Gofton, born in Kent, who appears aged 22 in the 1871 census, with Joseph and Dorothy Gofton ( both aged 65 ), is their daughter. The census actually says she is their daughter, but actually the census-taker was wrong, for some reason.
This Elizabeth Gofton aged 22 who appears as the daughter of Joseph and Dorothy Gofton in 1871, is actually their daughter-in-law, not daughter. She was the wife of Ralph Gofton born 1838, who appears to be the second son of Joseph and Dorothy Gofton. She was married to him in London in 1867. Her maiden name is Elizabeth Mary Seggie. Her apparent oldest son is Edward, aged 1, correctly described as the grandson of Joseph and Dorothy.
In 1881, she is living with her husband Ralph and six children including Edward who is now 11, and she is still correctly described as from Kent.
In 1883, this family moved to Queensland Australia. Ralph died in 1914 and Elizabeth in 1940. They had about 13 children in total.
