I don't have any specific info on these particular dwellings but, in general, where properties were built "off" roads (in courts and back terraces in the early/mid 19th C.) the names were often chosen by the builder or owner of the parcel of land.
This is why Hull had so many "Terraces", "Places" and "Buildings" where the actual name was the same (Ada's, Frank's, Mary Ann's, etc). The builder would typically use his surname or his children's names for his latest enterprise.
My guess is that Mr Staves, the builder, built Staves Buldings.
Hope this helps.
