carol,

Have checked the 1841 census and found 2 Mary Rudge entries for Ruardean 1 married the other single aged 45 address says "street"

Her occupation is shown as Shop Keeper

2 entries for Joseph Blanch

Ruardean

Joseph B Blanch aged 25 Quarryman

Others listed above him in same household? are

Cornelius Blanch 25 Quarryman
Ester 30
Tom 6
Emma 4
Pricilla 1

The other Joseph is listed at Newmans Bottom Dean Forest aged 45 and a Collier
looks like he is on his own.

Hope thats of some use

Dave
