It would be alot easier if you jut said what you were looking for AND spell checked your posts, to make it easier for people who want to help.
Marriages you mention
1923/C2803 Wallace Lavina Lousia Beaven Albert Culley
1936/C1146 Davies Margaret Beaven Albert Culley
Now we know we are looking for BEAVAN not BEVAN.
1960/C4479 Albert Culley Beaven Henry Albert Edith
1958 Albert and Margaret lived at 45 Lancaster Street, Townsville.
We cannot access BDM Deaths after 1964 so it might be an idea to search for Townsville Cemetery and see if Albert is buried with Margaret.
Purchasing the marriage cert should give you the names of Margarets parents.
