Question

How you see or imagine the families in the 22nd century?

Answer 1

there will be no families.

Answer 2

Less inbred than they are now.  It has become more fashionable for the younger generation to reach out of the Royal inbreeding gene pool to widen things out a little.  Even the youngest (from William on down) are less inbred, healthier looking, and better looking than their parents.
