I've been out all day and had no internet signal
Steamer could be a possibilty. As could calico print stearer. Sheep shearer I'm not so sure about.
Stear/Steer is the Scots for stir....so a stearer could potentially stir something??
The girl is Elizabeth Holland aged 13 at Riccarton. Her 11 year old brother Thomas is also a stearer.
There are other stearers among their neighbours and tearers too.
