Hi Adi
The baptism of Mary Ann FURMINGER 1853 Bredhurst is on the IGI
http://www.familysearch.org - daughter of Francis and Sarah.
Looking at the 1891 census for Newington, Kent RG12/717 folio 111 page 15:
Joseph FURMINGER head unm 53 (no birthplace given)
William ELDRIDGE bro in law mar 35 b.Walworth
Mary A sister b.Wouldham
I would, with certainty, say that the enumerator has made a mistake ie. he has accidentally missed Joseph's place of bith and entered it agains William then put William's place of birth against Mary etc. - this would all then make perfect sense.
Is the mix up of birth places for William, something that has happened with Joseph.
I'm not quite sure what you mean here as I don't see anything confusing about *your* Joseph's place of birth except that it has been listed as Bredhurst on one census rather than, as it should be, Walworth.
