I couldn't see a likely Ellen living with a John Kneale in 1861 [see Brian Lawson's census indexes: www.iomfhs.im/lawsons/LawsonBMD/census/census_index.html?Submit=Census+Indices]
I widened the ages for 1851:
Ramsey, College St.
John C Kneale 39 Labourer formerly weaver b.Ireland
Mary Kneale 38 Ditto b.Ireland
John Kneale 12 shoemaker app. b.Ireland
James Kneale 10 scholar b.Ireland
Charles Kneale 8 Ditto b.IoM Ramsey
Wm Kneale 6 Ditto b.IoM Ramsey
Eleanor Kneale 4 b.IoM Ramsey
[Very young at 16 to be married in late 1862, but perhaps her death age was correct!]
I couldn't find a likely Ellen b. Andreas with father John - only this one other Ellen in Onchan, which I don't think is her:
All b. Onchan.
John Kneale 38 Farmer
Isabella Kneale 42
Ellen Kneale 6
John Kneale 4
Joseph Kneale 9
William Edmund 14 nephew
The Ramsey one a possibility?
Perhaps Sylvia will find some more.
