Looking at the 1841/1851 Census in FOD Gloucestershire, and the Parish Records, there appears to be quite a few RUCK's including

1841 Census Dean Forest, Ross, District 20, Page 2

John RUCK - age 50 not born in County
Susanna RUCK - age 40 - not born in County (born West Bromwich, Staffordshire 1851 census) and their
children

And on the 1851 Census for West Dean there is an Edward RUCK/RUCH - age 50 who is a Blacksmith - spelt REUCK on the 1861 census.
