On the subject of duff information on Ancestry trees, someone has got a mix-up between 2 William Corrises who were born circa 1855, both with a mother Eleanor.
So there's the William Henry Corris,bap 29 Oct 1854 Patrick, to William Corris and Eleanor Killey, who appears in the 1861 census age 6, and in the 1871 census age 16, with both parents and a younger brother, Joseph b 1859, which I put in an earlier message.

Then there's William Robert Corris bap 17 June 1855 Patrick, to John Corris and Eleanor, who, with a bit of digging, turns out to be Eleanor Callister. This is their marriage, which conveniently gives ages:

This William R Corris in 1891 is in Dalton in Furness with his mother, Eleanor nee Callister, widow of John Corris, and 2 nieces:

Then in 1901, here's William R Corris:

Thos Quilliam is head of household b IOM
Eleanor is G mother, with G crossed out, widow b IOM
William R Corris is brother in law unm labourer at shipyard b IOM

The person who submitted the tree to Ancestry has got her Eleanors confused. She's written it as though Eleanor is the widow of William Corris ( and therefore nee Killey, although she doesn't suggest a surname for Eleanor ) But she's submitted Ancestry census pages which in 1891 and 1901 show Eleanor Corris nee Callister, widow of John Corris.

I'm wondering whether this is the burial of Eleanor Corris nee Killey, William's widow:

CORRIS, Eleanor 63 Fox 2 Jan 1883

Does this agree with your information, Gillian ?
