What is Jesus Christ's mum's name?

Jewish men were referred to and known by their father's name such as Judah ben (son of) Jacob.

Perhaps during Jesus' time unmarried daughters were referred to and known by their father's names as well, for example Dinah bat (daughter of) Jacob.

We at this point in time be do not remember or know Jesus' mother, Mary, father's name.

But another factor is that the married women of the day were known by their husband names such as Joseph the Carpenter's wife, Mary.

We do know her today as Mary the mother of Jesus the Messiah.
