One would be tempted to put mian desire and toil will
in the Tuiseal Ginideach after de réir according to
but it would be a mistake.
Mian and toil are already causing
the Tuiseal Ginideach of bean.
In such phrases only the last word

it would be right to put them in the Tuiseal Ginideach:
de réir a méine according to her desire
de réir a thola according to his will.
