1. Who knows? It is possible that a new ring be made or purchased. It is possible
that Harry be allowed to choose a ring from the Windsor collection. Wait and see.
2. Not unless Charles is King. Under Letters Patent of George V, Harry's children will only bear the peerage
title that he will be given upon marriage. Only the children, grandchildren of the
monarch, and the eldest son of the eldest son of the Prince of Wales are
supposed to be royally titled, but there are exceptions. BOTH of William's
children were allowed royal titles under Letters Patent issued by Elizabeth II.

3. Maybe, maybe not. Children are always welcomed.
4. Parliament rules who is the next monarch. Under current law, Harry is
in line after Charles, William, George and Charlotte. For Harry to become
the next king, Elizabeth, Charles, William, George and Charlotte would all have
to die, or become monarch and abdicate in favor of the next in line. Abdication
is seen as a CRISIS, a bad thing, a dereliction of a GOD-GIVEN duty to serve.
Abdication is not done unless there is a serious crisis.
And do you want all of these people to die?
5. Harry's wedding will most likely be televised since he is the son of the Prince
of Wales and the ever-popular Diana.
6. Hopefully. There will probably be some jealous people, though.
7. Diana had a will. She may have willed jewelry to her sons, so the wives
can wear the jewels. Some jewelry was the property of the Spencer family,
and must stay in the Spencer family--like the Spencer Tiara. Some jewelry
owned by Diana was stashed away for her sons... Harry had saved the
engagement ring, but gave it to William for Catherine.
8. Yes. Harry has a public role so his wife will take on one, too.
9. Perhaps Kensington Palace, but who knows... There are royal residences
throughout the UK that the Queen may open for Harry's use.
10. Hopefully. And, for a short time, at least, all eyes will be on Harry's wife because
she is new, just as all eyes were drawn to Sarah, Duchess of York, and away
from Diana, upon marriage to Prince Andrew. But, Harry and wife won't be
King and Queen Consort.
