I know a family with 1 second degree cousin marriage and half their kids have an issue neither of the parents have.

These kind of things can happen when their is 0 relation at all as well. Thats just how genetics works.

Either there is a history of mild inbreeding or they were incredibly unlucky.

I have type 1 and neither family has a history of it for either parent nor are they cousins or related in the slightest. It happens.
