Hi Leah Although I'm sure your Roylance's are related to mine,at the moment I can't prove it. My great great grandfather William Roylance, left Runcorn and moved to Manchester about 1870, some of his family brother's and sister's etc stayed behind.one of these will be your Roylance. I don't know if you have the 1881 census or not, but I have found onle three family's living there.
William and Sarah Roylance living at Robert Street, Runcorn.
Edward and Eliza Roylance Living at 6 Bentick Street, Runcorn
Emma Roylance, aged 27, although she was not married at the time of the census, she could have been married very soon after. 53 Waterloo Street Runcorn.
I think one of these will be the parents of you Roylance.
If you have not got the 1881 census, I will email you a full printout that gives all the members of the family and there occupations etc.
