I am looking for the Barkers of Yorkshire England. William Barker born about 1822 married Sarah Nellis(t) in Yorkshire England 18 Mar 1848. The arrived in Ontario Canada with two sons Robert and Abraham sometime between 1850 and 1852. The marriage registation listed William's residence as Gristhorpe in the District of Yorkshire, profession labourer, father's name John also labourer. I am looking for William's parents and siblings. Any help would be greatly appreciated.
