"Appears she married John Joseph O'CONNOR in Qld in 1910, the year after Jack LLOYD died in Cairns. (This can be found in the QLD BDM site) They conducted a florist business in Stanley St, Sth Brisbane. Can't track J J O'CONNOR after that. Next of course she marries F COOPER as LLOYD in 1926."
There is a margin of doubt about the relevance of this marriage as Gertrude did not use the name of O'Connor when she married Frederick Charles COOPER.
