It is well known that Leigh Brackett has a group of stories that share a common setting, and that those are based on the planets of the Solar System primarily on Venus and Mars

However, there is much other SF included in 50+ short stories and ten novels, including the books with Eric John Stark on Skaith.

It appears that she did indeed intend them to share a common history and setting.
