Hatherleigh is some 16.5 miles from Colebroke. Hatherleigh PRs are available via FamilySearch and there is an OPC for the Parish. HOWEVER, a William & Susannah TUCKER baptised 7 children at Hatherleigh between 1802 and 1818, with the father described as a labourer on the post 1813 baptisms, abode Highampton.
The children baptised at Colebrooke are to a William & Elizabeth, not Susannah. William wasn't a cordwainer either.
There is a Colebrook in Plympton St Mary and a William (cordwainer) & Susannah baptised 10 children there 1796-1814. So it is unlikely that the Hatherleigh family are one and the same.
