Dead or alive

Do you have any information about the Duftons?
We are always keen to obtain more pieces of the family history jigsaw.

Or, do you have information about any of the following elusive Duftons?

Joseph Dufton was born 1842, he appears on the 1851 and 1861 census living at Hutton in the Forest. He married Agnes Sanderson in 1864 and they have two children born 1865 and 1868.  Agnes appears on the 1871 census, she is recorded as married, and is staying with an aunt.  The two children John and Charlotte are staying with their grandparents. The elusive Joseph is not on the 1871 census.  Agnes remarries in 1880, and in 1884 Charlotte marries, her marriage certificate states that her father Joseph is deceased. All the indications are that Joseph died about 1870, but there are no records of his death.
However, in 1892 Joseph's uncle, Richard Dufton, leaves a third of his estate to Joseph in his will.  Richard lived locally, and was in a situation to know all about Joseph.  So why leave an inheritance to a nephew that has died?

George Dufton was born at Haydon Bridge in 1814, he was the son of Thomas Dufton and Mary Dobinson.  There is no further record of George until the baptism of his daughter Grace at Kirklinton in 1833, his wife is listed as Mary.  They are newly arrived at Kirklinton and the records indicate that they are from Ivegill, the home of his parents some thirty years previous.  Where did they go? As there is no further record of the family.

In 1838 James Dufton, his wife Sarah Thompson and their three sons left Askham in Westmorland to settle in Wabash county Indiana.  Their grandson Richard Dufton moved to Sedgwick in Kansas.  Do you have any information on the Kansas and Indiana Duftons?
