Hello again
Not sure how much detail you are interested in on Edward but this is a death notice for one of his brothers-in-law. It lists all of Edward's siblings - they match the ones listed in his mother Jane's 1933 death notice I posted a link to earlier.
The West Australian, Thursday 19 May 1932
BLENNERHASSETT. — On May 17, at St. John of God Hospital, Subiaco, Jim, beloved brother-in-law of Jane (Mrs. Smart, Sydney), Eward Bousfield (deceased), Harry Bousfield (United States America), Maud (Mrs. C. J. King, Claremont), Ruth (Miss Bousfield, Park-street, Subiaco), Fon (Mrs. Pringle, Kalgoorlie), Sydney Bousfield (Daglish). Peacefully sleeping after a long and painful illness.

The West Australian, Saturday 19 January 1946
BLENNERHASSETT. — On January 18, 1946, at her residence, 142 Park-street, Subiaco, Rebecca, widow of the late James Blennerhassett, loving mother of Rodger, Jim and Peg, loving sister of Ruth, Maud, Fon and Syd, fond mother-in-law of Reg; aged 56 years. At rest.
So he also had a sister named Ruth; she must be the one listed above. The Sarah (known as Fon) who married Pringle was also a sister of Edward, not a daughter. Ditto for Maud & Jane - Maud married in 1911 to Charles J KING in Claremont (reg 12) though I can't see Jane's marriage to SMART; possible death in Ryde NSW in 1937. Maud's death notices are here:
