I have found two separate baptism records for John George Le Boutillier Diamond: one on 23 Jan 1851 and another on 28 Aug 1853. Both were done in Chorlton-upon-Medlock, Lancashire. I have been able to view (on Ancestry) a scan of an original 1853 register and I see that John's sister, Jane Amelia, was also baptised at the same time. Was this kind of double baptism common and does it tell us anything more than an ordinary single one. Is it significant that I can find no further records (either census, marriage, or death) for John.
