Hi David,
You know that
Ivor Hutchfield JONES and
Gladys Marie McNABB
were married December 30 1924.

In Edmonton? -
In those days - people sometime published an announcement of the marriage -some very simple - others with some/much detail.with names of the parents, wedding attendants etc.

The Marriage Registration/Genealogical Marriage Registration - will show the names of Bride and Groom, names of both sets of parents etc.
This can be obtained from the Govt of Alberta Vital Statistics Dept Registry Office. The cost in the $40 range.

If you know the name of the Church-or Religion of the family- There may be records.

Death Registrations for Ivor Hutchfield JONES, Gladys Marie McNABB - may show the names of the parents. Much depends on the knowledge of the informant. *most will know the fathers name - not always the mothers? [she is always just mom.mother]
If they have passed away - and you know the name of the Funeral Home in Charge of Arrangements - they may have taken information for the Registration of Death.
Cemetery Office can advise re name of Funeral Home.
Cheers, Stella
