I couldn't find any connections for those addresses, other than the one obvious one, the St Augustine Street address, which has a connection to later records (already mentioned).
Looking at the families it appears that Julia was the wife of James Morris (1974-1906) and the daughter of Robert and Belinda. Jayne has stated James died in 1906 but (I don't think) she gave his surname.
Note that Julia and James were living next door to the Scaifes, namely John Gibson Scaife and his wife Jane (parents of Joseph, born 1870), on the 1901 census.

There are some FindAGrave records for some of these people and with various relationship links (although I'm not convinced by the link to Joseph Scaife (1879-1922)).
