Hi Tricia
Welcome to Rootschat
Virtually all of Beds marriages and baptisms pre 1812 have been extracted onto the IGI, which you can check out yourself at
www.familysearch.org.
You'll find three entries in 1809, two of which are member submissions which are usually unreliable, and the third is the extracted entry which you can rely on (in this case the members have actually got it right)
The parish register transcription adds no further detail to what's on the IGI
For what I would have thought was a unique name I'm surprised that there were two earlier baptisms in the nearby parishes of Meppershall in 1807 and Campton in 1774
You'll also find his parents' marriage in Southill in 1802 - the transcript describes his mother, Sarah Porter as being from Shefford, which was actually in the parish of Campton.
