Ideal landing with DHC 6 in cross wind is flaps 10/speed 85. Or even flaps 0/speed 100/condition levers max after touchdown if runway lenght permitting.
Best technique to maitain axis: keep the nosewheel up by pulling progressively the control column vs decreasing of speed as far as possible (it will drop by itself at around 50 -40 kts)
Below this speed you can stop the DHC 6 easilly.
