Bridal Party Order-dumb question

okay here goes my dumb questions-

BP order in reception ??

MOB
MOG
BM & GM
Maid of Honor & GM
Matron of Honor & BM
FG & RB
Bride & Groom??

Also are they introduced by first name only??

BP order in church?? so confused

TIA

we're doing

parents of groom
parents of bride
(rb and fgs - if we had them)
BM and GM
Maid of honor & BM
(matron of honor) & BM) - if we had them also
us

same order for ceremony (you could also put FG and RBs right before bride)
