You would need to view the original parish records for Erith, Kent - which would probably be kept at the local Records Office.
Alternatively you could possibly order the film of the parish registers from your local LDS centre.
The database that the Ancestry entry is from is the British Isles Vital Records Index - which has been done by the Church of the Latter Day Saints - very similar to the IGI.
Just come across the above reference to Thomas Allen´s birth.
I´m assuming this is the Thomas Allen who married Ada Amelia Day whose parents were Henry Allen and Rebecca Elliott and if so he was a great uncle of mine.
