I drove a coach for Trailways for two years and carried a
lot of Amish families. They seemed to have an inordinate
number of offspring with abnormalities that we associate
with inbreeding. One family had three adult offspring that
were all handicapped. Not very scientific research, but I
always wondered if with the small communities that they have
if the gene pool wasn't too small. Most of them were very
nice people, it always hurt to see this.

My family has the same, but there’s no inbreeding. Anecdotes like this are not enough to make policy.
