I can see a John Everleigh in Ottery St Mary in the '41 and '51 Census - but this appears to be the John that married Elizabeth Clay, Dec 16th 1838, father Robert.
A John Eveleigh, age 32, was buried at Yarcombe** on Dec 13th 1846. Calculated Year of Birth would be 1814 - yet to find this John on the '41 Census.
** The burial register says Yarcombe but FindMyPast has transcribed as Upottery (the entry above reads Upottery)
Looking at the register. It looks like the register were burials at Upottery and his abode was Yarcombe. Either Yarcombe was too small to have own graveyard or he had more connection with Upottery
