From a royal geneology site:

Any thoughts on how this is possible?

One of the babies must have died in the womb at three months gestation. The other twin continued to grow to seven months when it died, and was stillborn.

I thought I was wrong once, but I was mistaken.

Maybe one died in utero months previous, while the other continued to grow, only to die at 7mos. gestation.

Just a WAG.

But wouldn’t the mother end up with one hell of an infection (which would probably have been fatal in those days, and she did survive 'til 1714)?

Hey, didn’t something like this happen recently, within the last year or so? The twins lived, IIRC, but they were born a couple of months apart. An early test revealed that one of the twins had some sort of defect(I believe it was a heart defect), that could actually be corrected, if they did a C-section, took out the twin with the defect, and did the surgery.

Here’s a short quote from [Parents.com](http://Parents.com)

"The death of one twin is not a rare occurrence. Frequencies range  
from 2.2 to 6.8% of twin gestations. When one twin dies, it may  
become what they call a “fetus papyraceous”. The fluid is reabsorbed  
and the fetus is compressed by the growth of the living baby. This  
happens in single pregnancy losses as well and is the basis for the  
tabloid newspaper headlines of “80 year old woman gives birth to  
baby” (or mummified baby). "
