Bluntisham baptisms have been extracted onto the IGI, but there's no sign of a baptism. Colne parish register hasn't been filmed by the LDS so doesn't appear on either the IGI or BVRI, nor is a transcript available from Hunts FHS. It's available though at Huntingdon records office - if you can't get there they run a reasonably priced research service.
Just looked at them on the 1861 census and find that his grandmother, Hephzibah (Hedge) Chandler was my 3xg great aunt; her elder brother Moses was my 3xg grandfather. Shout if you need any information on the Hedges. I haven't researched Hephzibah's children or grandchildren.
