I think they were called Cherry Binn and Sarah Fimm. Odd that because angels are supposed to be male. Such a silly solecism to make in a story which in other respects is so very obviously true.
The accounts differ, and not all gospels define them as angels. Two record one person(?) at the tomb, and the others record two. No names are given, but Matthew describes the person as a 'young man', Mark describes him as an 'angel', Luke says 'two men', whereas John goes completely over the top, as usual, by describing two seated angels, one at the foot and one at the head of the place where Jesus had lain.
