Have had a look through some transcripts for East Peckham PR's, but not had any luck with a baptism or marriage for Richard. I found his burial, 27 Feb 1848, Holy Trinity, East Peckham, aged 54. Also found what is probably the burial of his wife, Elizabeth, aged 100! On 23 Mar 1890, same church.
I found some of the baptisms for their daughter Elizabeth's illegitimate children, also at Holy Trinity. Sometimes a supposed father is added to the baptism record, but there don't appear to be any notes on the transcriptions I have concerning any fathers. Other parish records, bastardy orders etc if available would be at the Centre for Kentish Studies at Maidstone, but I think there is a bit of an upheaval there at the moment because they are moving, so I don't know what can be accessed at present.
