I don't know what registry you used, but DM was definitely at St. P.  She was there when Fr. Libietis was pastor,  and through Fr. Heggenberger. I am sorry your information is incomplete.  As for no kne ever hearing if her, I say who did yoh ask?  For that matter, I have no idea who you are, perhaps you were never really there.

I know very little about St.P.  But I think I know who DM is.  In fact we have conversed together on the phone.  I think it was in that very chapel where DM claims to have had a vision of the Virgin Mary in 2004 right in the middle of Sunday Mass.  I believe, furthermore, according to her own testimony, that Bp. Fellay himself was disposed to believe that she had had this vision, and subsequent ones, as well.  If this is the same DM, we know that Bp.  Williamson takes her very seriously to this day.

If I am incorrect in these assumptions, I have reason to believe that DM will be the first one to jump down my throat and offer instant correction.

But, as to her having attended St. P's, I have absolutely no doubt.
