[edit] Her birth date
Although there are many web sites that give her birth date as September 11, there are more that give it as August 29 (OS), for example, these: [1], [2] and [3]. This one gives both [4], but clearly one is in error, because the difference between the two calendars in the nineteenth century was 12 days. I suspect there was an initial miscalculation of the NS date, based on the 13-day difference in the twentieth century, and many subsequent articles used that without rechecking.
