Weekly Puzzle - Mary Jane Trindle Noffsinger

On 16 Jun 1847 Mary Jane Trindle married Andrew Nofsinger in Knox County, Ohio.  

Andrew and Mary Jane were listed in Clay township, Knox County in the 1850 census with one son William age 2. (1)

On 5 Jan 1858 Andrew was married a second time to Helen Wood.  (2)

In 1860 Andrew and Helen were living in English, Keokuk, Iowa.  Five children are listed: Thornton (same as William above), James age 10, John age 8, Albert 2 and Mary A 2m.  It would seem likely that the first three are all the children of Mary Jane which puts her death between 1852 and 1858.  (3)

Further clarification comes from the 1856 Iowa census (English River, Keokuk).  Andrew, William T, James and John are living with Lucy Nofsinger age 70 most likely Andrew's mother.  Andrew is listed as a widower. (4)

So Mary Jane died sometime between John's birth in July 1852 and the date the census was taken in 1856.

Her tombstone is found in South English Cemetery listing both a birth and a death date of 1 Feb 1855. (5)

All well and good, but who is Mary Jane?

In 1850 William and Mary Trindle were living in Licking county (next door to Knox) Living with them is Matilda who was born in 1838.  Other children that have been suggested for this family are William Alexander bn 1822 (moved to Indiana), Rebecca bn some time after 1823 and Samuel bn 1837 (died age 20 buried in same cemetery as father).

This family configuration definitely could accept Mary Jane bn 1827 and perhaps still unconnected individuals born in Ohio.

If this is the correct family, does anyone have source information to prove it?  Does anyone have information to prove otherwise?
