There was a book published in 1967 called "Gloucestershire Woollen Mills" by Jennifer Tann. It covers the whole of Gloucestershire - not just the Stroud valley. Though it gives some names, these are usually mill owners, and not mill workers. There are illustrations of some of the mills if you find out where your ancestors worked.
In your list of names of interest, I noticed Gould and Reece. I looked these up in the index, but there was no reference to either.
Under the heading of "Thrupp mill" - it says there was probably a fulling mill there from the 17th century. Run by members of Wathen family in latter part of 18th century. Later leased to John Ferrabee in 1828. The mill has since been demolished.
It also appears that few records have been found for this site.
