The christening has been transcribed on FamilySearch
https://www.familysearch.org (free to search) although the church is not specified:
John Parsons ROBERTS, son of John ROBERTS and Eleanor, christened 2 Jan 1852, Shrewsbury.
At least 2 other children of John and Eleanor are christened in Shrewsbury around this time, including a Lucy Hayman ROBERTS (at St Giles & Holy Cross), so this marriage looks possible for the parents:
