Hi Tisha
My great,great grandfather Thomas Grantham(born 1820) was the son of William Grantham/Sarah Winter.He married Elizabeth Powell at Ettington on the 5th April 1844.They had at least eleven children and seem to have moved around the area between Banbury and Shipston as the children are born in a few different villages.Cannot find a baptism for my great grandmother ,Dinah Grantham, or my grandfather Josiah Fisher.This does not mean they were'nt baptised as my father was baptised at home because they thought he would not live long.Perhaps they were all home baptisms and thats why no record exsists,just thought i would mention it as a possible reason you are having trouble finding baptism records.I have seen some lists on parish registers as "baptisms not bought to church"but i think it was down to the individual vicar to record them.
Thomas Grantham died on 26 December 1879 in Pillerton Hersey of pneumonia.Elizabeth moved to Aston ,Birmingham with Dinah who married my great grandfather George Edwin Fisher in 1882.I think Elizabeth died in Bromsgrove in 1907 but i have'nt sent for the cert.yet.Hope that explains how i am attached to the granthams and helps with your Thomas query.
Best wishes,Colin.
