When I looked at the promethease results I thought it was interesting, but since I already did a Y-DNA test I really didn't not pursue this topic much and it would take some time to go back and remember it all. Dr. Turner (apturner) spent some time looking into this and gives her findings a few posts up from this. The following is her conclusion with respect to using ancestryDNA for haplogroups:
"Bottom line, I don't think the AncestryDNA results will be very useful for many people, although there are some interesting SNPs"
She did mention working on a spreadsheet that might help in your particular case, so I suggest looking into that.
Sorry I can't be of more help,
