^ Precisely !

According to what I feel is that the title Aal-e-Imran refers to the Family of Amram and Zakariyyah (AS) was also part of it. But if Imran refers to only Maryam(AS)'s father then he would not even be directly related to Zakariyyah (AS).

For this reason I am 50:50 about the name of Maryam (AS)'s actual father, because the designation in the Qur'an could be referring to her ancestor.

The name of Mary's father actually can't even be found in the current accepted Bible, but in the Bible Zakariyyah (AS) was a Levite and it can be seen from apocrapha books such as Gospel of James that Mary's father was named Joachim and he was noted as a saint a very pious man from the house of Amram. People used to associate his piety and the prophethood of Zakariyyah (AS) as to the house of Amram and under the tribe of Levi in general, who were known as the tribe of the priesthood, because most Jewish priests came from that tribe.

According to us however we refer to both the ancestor and the father of Maryam (AS) as Imran, but I think that might be out of convenience rather than anything else. It could well be that the father is really Joachim or may be still that Joachim had another name which was Imran/Amram, Allahu'alim.
