Hi and welcome to Rootschat, was he the George Holroyd who married a Nanny Kilner 26th June 1836 Almondbury, All Hallows, as both 1841/51 census he and Nanny & family are showing with a Hannah Taylor, in 1851 shown as aged 86 Aunt.
Keyboard86
EDIT A Nanny Kilner born 16th February 1807 baptism 15th March 1807 Huddersfield Father Abraham Mother Hannah Taylor?
Hannah b Dec qtr 1844 Huddersfield is Hannah Taylor Holroyd mmn Kilner.
Seeing as the first apparent born was a John, wondering if he is the George Holroyd baptism 10th November 1805 Elland, St Mary abode Rastrick Father John Mother Mary?
