In my tree, Willian Henry Smith father is called James Smith and Bridget, but I’ve only found this as a potential from using census records.
I have an ancestry result for a marriage between William and Rose from BMD in Dec 1984 but I’ve not found the details on the Lancashire site.
That’s a cert I need to order at some point to confirm both of their parents for definite. But I do know William had a sister called Kathleen.
