Sorry I'm a bit behindhand replying here: I believe (but can't prove) that Alice Johnson was the illegitimate daughter of her older "sister" Elizabeth (look at the age gap), which explans the absence of a father's name on her marriage cert. There's a very iffy baptism for Alice, daughter of Thomas Johnson (weaver, of Bosden) and Elizabeth at St Mary, Cheadle on 1 October 1826 - possibly a combination of her mother and grandfather's names. (I can't find any other Alice Johnson who matches this birth date.)
William Gosling was possibly the illegitimate son of Anne Gosling, baptised as William Rowland Gosling in Bosley on 26 Feb 1825 - that's the best match I've found so far. :/ On the 1841 census he's a 15 yr old silk weaver lodging in Bosden, which isn't a lot of help.
