Paul, 

So far as I am aware wattle & daub is used only as non-structural
infil panels in timber framed buildings.

However, where abouts in England did your mother come from?

We live in Lincolnshire in a 'mud & stud' cottage, which  is a sort of
hybrid of a cob and a timber framed building.

Mud & stud buildings contain a (relatively light weight) timber frame
(either just posts seated  on pad-stones or else posts joined into a
sill-beam over a plinth.) The walls are then built up as follows;
horizontal rails are fixed between the vertical posts, vertical laths
are fixed to the rails, and a cob-like mix is then built up around the
laths. Mud and stud walls are typically 8 - 12" thick, making them
thicker than wattle & daub (typically 3-4", I think), but thinner than
conventional cob. The timber frame is only visible internally. In
theory both the frame and the earth wall have a structural role. (Our
cottage is a little over 300 years old).
