Alexander of Saxony Gessaphe and his brothers also have a female line to Maria Theresia but it ends with them.
Come to think of it. I believe that Anne of Romania's granddaughters are the only existing lines that can continue it.
: Just how many maternal collateral lines of
: descent survive from her, anyway? One would
: think that it would be an extensive one,
: since she had a total of ten sisters. But I
: know of only one with an unbroken
: matrilineal descent surviving today:
: Archduchess Maria Carolina of Austria.
: Perhaps it's no surprise, given the fact
: that this unfortunate queen of France was
: born in 1755 -- an age of high infant and
: childhood mortality rates. And there are
: numerous other ways in which one's
: matrilineal descent can expire -- e.g.
: deaths in young adulthood unmarried
: (remember that poor medicine has been the
: rule throughout history), perhaps death from
: complications in attempting to give birth to
: one's first child after marriage, women who
: took up religious life or for some other
: reason never married, childless marriages
: (for practical reasons I count any union
: such, if it failed to produce a single child
: reaching adulthood), marriages that produced
: only sons and no daughter.
: So of her ten sisters, I believe only a few
: survived to adulthood, married, and produced
: daughters. But then, the same story would
: repeat itself in the next generation,
: regarding those nieces through her sisters
: (e.g. deaths in infancy or childhood, etc).
: Or perhaps I'm mistaken, and the maternal
: collateral descent from Marie Antoinette is
: extensive -- meaning that there are other
: surviving lines. Does anybody know of
: additional ones (whether from Maria Carolina
: or another sister, perhaps from another
: niece)? It has been said that the late
: Queen Anne of Romania represented such a
: line: since she herself was the mother of
: five daughters, the said line is still alive
: and flourishing.
