After a LOT of census work (with more to go), I currently think the most likely John Burns death is 1848 Apr-Jun in Chatton (Glendale Union registration district).
That matches the following:
1841 census, John and Ann at New Hall, Chatton, Northumberland with children Margaret, Mary, Isabella.
1851 census, Ann widow at New Hall, Chatton, Northumberland with children Edward, Isabella.
In the process I seem to have found a lot more children. Here's the full set (work in progress - still quite tentative):
William b1811 Kyloe m Jane Alcorn 1836 d1901
John b1811-14 d1838 [as per news item mentioned in this thread]
Thomas b1814 Kyloe m Eliza
Jane b1816 Twizell m Thomas Heslop 1845 d1918
Martha b1817-19 Kyloe m Robert Percy d1874
Edward b1820 Kyloe m Ann Mole 1862
Mary b1821 Kyloe m Thomas Fulton, no children
Margaret b1826 Kyloe m William Bolton 1848
Isabella b1827-33 Kyloe m Thomas Crozier
The main thing I'm lacking is birth records for the above (except Jane). That would be very welcome confirmation. Can anyone help, please? The parents should be John Burns and Ann Clark.
And a key mystery is where most of the children were in 1841, if I'm right about the list above. William was probably the only one already married; Jane, Edward and Margaret were not, and the others probably weren't (based on children's ages in later censuses). And yet only Mary, Margaret and Isabella were with their parents.
Some additional findings which add evidence for family connections:
- Two of the Percy children (Martha's children) were with grandmother Ann in 1861 at Chillingham.
- Isabella's unmarried daughter Anne Crozier was with uncle Thomas Burns in 1881 in Duddo. (Not to be confused with Jane's married daughter Anne Crozier.)
- William's son John, and Thomas's son Ralph, and Margaret's daughter Mrs (Ann) Cook, all appear in newspaper articles about Jane Heslop in 1916-18.
Another thing that bothers me is that in the 1916-18 Jane Heslop newspaper articles, Margaret seems to be described as Jane's "youngest sister" - that put me off accepting the 1841 census which includes Isabella, and I'm still unsure about it.
My census work made a lot of use of Ancestry automatic suggestions (though I am critical of them).
