I am trying to verify the baptism/birth of a Robert Thompson who was purportedly born around 1811 in Chatton. He married Elizabeth Clark on 1 May 1837 in Alnham and he appears on the 1841(aged 30), 1851(aged 40), 1861(aged 50)& 1871 (aged 60) censuses, always born in Chatton. Can anyone help me find his baptism?
