Unfortunately this film is 'locked' and you can only see the actual image at an LDS centre or 'affiliate library'. You could check your local library to see if it's available there - my local library is part of the bigger city library system, and they are deemed an 'affiliate library'.
The transcription from the Kent marriages film also gives them as both 'single' but no ages are transcribed, so it's possible they are not recorded on the entry. As this is before 1837, it's also unlikely there will be any fathers' names given either.
If you search the film number you have given for 'Mummary', there are 6 other records with that name.
A Thomas Mummary 29 Nov 1823, aged 62.
A John Mummary 1 March 1821, aged 39.
An Abigail Mummary 2 June 1833. aged 0.
and 3 marriages of Mummary girls, Elizabeth 1815, Sarah 1834 and Mary 1823.
