Thanks for that Len, not solved but a bit closer, putting it all together we now have:

Ballaugh parish

William Quine
Married Jurby 18 JAN 1800
Ann Christery b 1775 d 8 April 1847
Children
Ann b Onchan 02 Jan 1803
John b Onchan 05 Oct 1804
[probably? Robert b Onchan 31 MAY 1810 Onchan, no mother named]

Family at Ballacorage, Ballaugh in the 1840’s or earlier
[ In 1703 John Corraige on this land]

1841 Census:- Ballaugh.
Ann Quine 60 b 1781
Robert 25 b 1816

1851 Census: Ballaugh
QUINE, Robert, Ballacorage, Head, Unmarried, 39, Farm 35 Ac & Prop, Onchan
With 2 servants

From MI: ROBERT QUINE of Ballacorage died 23 Dec 1859 age 49 years [b1810]

A George Quine in 1867 had around 30 acres of land at Ballacorage
including [Ballacain part of Ballacorage]

1861:-Census Ballaugh
George Quine 31 Ships Smith, America [A boarder in Ballaugh.]

Possible scenario;
Robert Quine of 1810 died in 1859 and the farm was inherited by either:
1] George possibly the son of John Quine of 1804?
2] Or George Quine is descended from an earlier family [based on John of 1804 dead and no heir]
3] George Quine is unrelated and just moved onto the farm

Assuming item 1 is correct:
John Quine married Ann Garrett 1828 in Ohio, possibly John of 1804 ?
