Maternal aunt with whom Timothy Eaton (founder of Eaton's) lived 1854

Hi,

I found this information:
In 1854, following the path taken earlier by three of his sisters and his brothers Robert and James, Eaton travelled to the Georgetown area of Upper Canada, where a maternal aunt and her husband had settled in 1833. He found employment as a junior bookkeeping clerk at a small general store in Glen Williams, just outside Georgetown.

Does anyone know the name of this maternal aunt or her husband with whom Timothy Eaton stayed?
