Try it, you'll find it fascinating.
I suspect it will change some of your ideas about "inbreeding" too ---- if you have some good GEDCOM's to feed it ---- and work seriously with it.
"For by diligent perusing the actes of great men, by considering all the circumstances of them, by composing Counseiles and Meanes with events, a man may seem to have lived in all ages, to have been present at all enterprises, to be more strongly confirmed in Judgement, to have attained a greater experience than the longest life can possibly afford."

| Very interesting - I've never heard until now of the Wright
| Coefficient of Inbreeding.
| The one I've always suspected of suffering physical consequences of
| inbreeding is Edward, Earl of Warwick. His parents were first
| cousins, and each were the product of so much cross-breeding
| themselves. Edward was reputed to have been mentally handicapped.
| It's possible Edward, Prince of Wales, son of Richard III, also
| suffered physical consequences of inbreeding. Richard III married his
| first cousin, sister to Edward of Warwick's mother. If I remember
| correctly, Richard III's son died as a youth of some illness.
| Lucky for her descendants, Margaret, Countess of Salisbury, took the
| extremely obscure Richard Pole as her husband and brought some "fresh
| blood" in.
