Two baptized on the same day though. 26 June 1825
Other one is John, son of John + Elizabeth Stevens
Find my past says John born 12 March(!) 1825
Launchbury website Mo found says John born 13 Sep 1813
Apparently no baptisms to John and Elizabeth Stevens at Bledlow between 1809 and 1814.
On a side note, on the lanchbury site, baptisms to John and Elizabeth Stevens of Hepzibah in 1815 and Isabella in 1821 have the father as a shoemaker, the 1826 baptisms have the father John as a farmer.
John Stevens, Elizabeth, Isabella, and Hepzibah Bailey (she seems to have married in 1834) are living together in Bledlow in 1841 (John is a Shoemaker)
