Ahhhh wayward, you were right! Her grave is apparently still there....
The skirt of Hagar was the area in which Ismail was raised. The house of Hagar is there. Her grave is near the third column of the Kaaba.What a surprise since no one, not even prophets, are supposed to be buried in mosques but in this case, the house of a maid is located next to Allah’s house! Hagar, the mother of Ismail is buried there. The Kaaba extends toward her grave.
I had this site in mind when I wondered if she was still there...a few years ago, this was the site of over a thousand graves, many in their own little miniature highly ornate tombs. The Saudis flattened them all and this is all that remains...site of future office buildings..they now threaten to destroy even Muhammad's grave for same reason, that no graves are allowed..
Historians and academics in the fields of linguistics and source criticism believe that the stories of Ishmael belong to the three strata of J, or Yahwist source, the P, or Priestly source, and the E, or Elohist source (See Documentary hypothesis). For example, The narration in Genesis 16 is of J type and the narration in Genesis 21:8-21 is of E type.
Islamic traditions consider Ishmael to be the ancestor of Arab people, excluding Arabs who are descendants of Ya'rub. Arabs who are from Ishmael-descendant tribes are occasionally referred to as "Arabized-Arabs" to highlight their ancestry. The Prophet Muhammad was of these Arabs. However, many modern Arabs also believe their tribes and houses to be of Isaac's blood line, in particular in Southern Palestine.
Jewish traditions are split between those, like Josephus, who consider Ishmael the ancestor of the Arabs, and those, like Maimonides, who believe that the northern Arabs are descended from the sons of Keturah, whom Abraham married after Sarah's death.

Judaism has generally viewed Ishmael as wicked though repentant (Whereas Christianity omits any reference to repentance which is sourced in the Talmudic explanation of the Bible . Judaism maintains that Isaac rather than Ishmael was the true heir of Abraham.
In some Rabbinic traditions Ishmael is said to have had two wives; one of them named Aisha. This name corresponds to the Muslim tradition for the name of Muhammad's wife. This is understood as a metaphoric representation of the Muslim world (first Arabs and then Turks) with Ishmael.
The name of an important 2nd Century CE sage—Ishmael ben Elisha, known as "Rabbi Ishmael" (רבי ישמעאל), one of the Tannaim—indicates that the Bibilical Ishmael enjoyed a positive image among Jews of the time.
Rabbinical commentators in the Midrash Genesis Rabbah also say that Ishmael's mother Hagar was the Pharaoh's daughter, thereby making Ishmael the grandson of the Pharaoh. This could be why Genesis 17:20 refers to Ishmael as the father of 12 mighty princes. According to Genesis 21:21, Hagar married Ishmael to an Egyptian woman, and if Rabbinical commentators are correct about Hagar being the daughter of the Pharaoh, his marriage to a woman selected by the Pharaoh's daughter could explain how and why his sons became princes.
However, according to other Jewish commentators, Ishmael's mother Hagar is identified with Keturah, the woman Abraham married after the death of Sarah, stating that Abraham sought her out after Sarah's death. It is suggested that Keturah was Hagar's personal name, and that "Hagar" was a descriptive label meaning "stranger".This interpretation is discussed in the Midrash and is supported by Rashi, Gur Aryeh, Keli Yakar, and Obadiah of Bertinoro. Rashi (Rabbi Shlomo Itzhaki) argues that "Keturah" was a name given to Hagar because her deeds were as beautiful as incense (hence: ketores), and/or that she remained chaste from the time she was separated from Abraham—keturah [ קְטוּרָה Q'turah ] derives from the Aramaic word for restrained.
It is also said that Sarah was motivated by Ishmael's sexually frivolous ways because of the reference to his "making merry" (Gen. 21:9), a translation of the Hebrew word "Mitzachek". This was developed into a reference to idolatry, sexual immorality or even murder; some rabbinic sources claim that Sarah worried that Ishmael would negatively influence Isaac, or that he would demand Isaac's inheritance on the grounds of being the firstborn. Others take a more positive view, emphasizing Hagar's piety, noting that she was "the one who had sat by the well and besought him who is the life of the worlds, saying 'look upon my misery.'"

“Ishmael is mentioned over ten times in the Qur'an....In the genealogical trees that the early scholars drew, Ishmael was considered the ancestor of the Northern Arabs and Muhammad was linked to him through the lineage of the patriarch Adnan."
