Over at http://www.romancatholicvocations.blogspot.com which is a great site, the header pic of the day is labeled as "French Norbertine Sisters in Rome" but they look a LOT like some Nashville Dominicans, to me.
I know the Nashville OP's habit was french-designed, so perhaps I am wrong and they took their design from the Norbertines, but check out the "vocations blog", picture - if you look to the bottom left (actually at about "8 o'clock") that sister seems to be Sr. John Peter, who you can see here, standing with her blood sister and fellow novice, Sr. Beatrice: http://nashvilledominican.org/News/Communi...ception2007.htm The other novices also look familiar as Nashville novices, and the mistress.
Does anyone know? I'm sure the blogmaster would want to be told if he had a wrong citation on his blog.
