Hi Sandra, this has thrown me completely. My grandfather was married and widowed before he met my grandmother, and he had 2 children from his first marriage John and Irene who moved to Birkenhead. I think the John A Daugherty in the 1881 census is my Grandfather John William Daugherty as the family address/parents names/fathers profession match that on the actual birth certificate I have. Also 1891 census backs this up with my grandfather listed as Herbert, which is a name the family knew him as. Am not sure if the marriage to Catherine Cowley is his first marriage, only because the childrens names and ages dont seem to tie in atall. Very confusing. But thank you for your help.
