OK - I;d misread it as his father being John Young, not his grandfather.
Following back I can see John, Martha's father, b c1827 in Manchester. On 1861 he has sister Augusta b c1840, also in Manchester with him (definitely him - he has Weavers living with him). This leads me to this on 1841, in Blackburn St. all listed as born in county.
