Hi Fizzy,
This looks like them:
HO107/1895/613 p 5
South Holle, Bideford, Hartland Devon
Mary MUGFORD Head W 49 F Pauper b Hartland Devon
William MUGFORD Son 10 M b Hartland Devon
Richard MUGFORD Son 8 M b b Hartland Devon
John MUGFORD Son 4 M b Hartland Devon
Looks like John senior died after 1844, or Mary can't get the ages of the children right.
Margaret is a house servant to farmer John Moss and his wife at Milford in Bideford, no sign of Darcus (?Dorcas), and there are two Elizabeth Mugfords listed. Both are servants, one in the house of a William Mugford, farmer at Forceswall, Bideford and the other at the house of William Dayman at Sinton, Bideford. Both born 1833 in Hartland.
