Brunotwo on Family Tree Circles

I have been searching for the baptism/birth of OBADIAH MILLTHORPE for the last thirty years. His death certificate of 1842 suggests a birth c1803, he is buried YKS Ecclesfield and in 1841 gives YES for born in Yorkshire. He was also married to a Mary c1824, she is also buried in Ecclesfield but I have never found the marriage. He married Elizabeth SWAN in Sheffield St Peter in 1836 - just too early for a father's name.
Any help most gratefully accepted.

Seeking birth/baptism of Dennis Brett circa 1780 or earlier, connection with NTT Edwinstowe.
