Franz (Frank) Gatzenmeyer - DOB query

I am wondering if this DOB is not quite right.

I started by trying to disprove a Tree Match to Franz Gatzenmeyer
and ended up grabbing the Marriage record for Franz and Elizabeth White in South Austalia.

This marriage registration did disprove the match in two ways, Father and Marriage Status.

However, it also brought about a query on the DOB for Elizebeth White

If Franz is 22yo in 1913, his DOB seems correct.
If Elizabeth is 26yo in 1913, her DOB seems a bit off. (Currently she would be 32yo)
Add to this that a 10 year age difference is pretty unlikely for a 20-30 year old wedding...

Hope this helps.
