NOTES: Imagine my surprise to run across this family connection
to Diana, the late Princess of Wales! For this is her family; indeed
Mary was born in the very house at which the Princess is now buried.
And despite my earlier skepticism, new information from Ernest O. Vincent
appears to support this connection. But see CAVEAT in notes on her
Mr. Vincent cites Complete Peerage, V. 7, p. 205 for further information on Mary's descent (I haven't checked it yet, at this writing). The wedding date above is from the old LDS chart, not the new information.
