Hello any one have this couple in their tree?

William Wilkinson married to Lindsay Hay Dalziel Simson (1836 @ Kettle, Fife)

or any of their children all born in Kettle:

James b 1841
George b 1837
John b 1836
William b 1848
Helen b 1845
Lindsay b 1853
Robert b 1843

Robert (b 1843) married Isabella Bell in 1866 @ Kettle and had a daughter Lindsay Wilkinson (b 1873 @ Kettle)

My gr.gr.grandfather David was born in Kettlehill, he was the son of Helen Wilkinson
(b1845).

I  have not had any sucess finding this family in the 1851 Census of Fife.  Anyone found any more information or researching this family?
