I have looked at one tree on ancestry which seems to have one of the children (William Harker Pepperell) apparently the son of Richard and Hannah, but he is actually the son of Richard and Frances. The death in 1840 of Richard Pepperell, I think relates to the Richard that married Frances because the burials of Richard and Frances both say of "Palace Street". Again on ancestry this death has been related to the Richard that married Hannah. So unless both Richards live in Palace Street which could have happened I suppose, I think that is also an error. There is a death of a Richard Pepperell in 1823, Exeter, aged 74 which means he was born in 1749, could not find any other in Exeter. I also could not find a burial for Hannah/Ann. Sally
