According to online versions of the original Greek:
Matthew has
Mariam (1:20) for
Jesus's mother and
Maria (27:56) for the other people named
Mary.
Mark only refers to
Jesus's mother in the genitive as Marias (6:3). Others are called
Maria (15:40).
Luke calls the mother
Mariam in all cases except for Acts 1:14 where she is
Maria. The others (including
Lazarus's sister) he calls
Maria.
John doesn't refer to the mother by name. He calls
Lazarus's sister
Maria or
Marian (or is that an inflection?) and all the others
Maria.
Romans 16:6 has a
Mariam.
