From what we know, HV1b2 is almost exclusively found in Ashkenazi Jews at a frequency of ~3%-3.54%, and Europeans of maternal Jewish descent. I am of the opinion that there are 3 potential origins for HV1b2, and I will explain the "evidence" in each case:
Theory 1: Levantine/Canaanite
A Levantine/Canaanite origin is supported by the presence of HV1b2 in a Romaniote Jew (from Larisa) - indicating the possibility of coming from an ancestral source. This is furthered by a study that showed that HV1b2 is very closely related to a lineage in Iraqi and Georgian Jews (the study seems to have been removed - I can no longer find it).
Additionally, HV1a'b'c (upstream of HV1b2) is present in a sample from the Late Chalcolithic (3800 BCE-4500 BCE) Israel. Similarly, HV1b1 is present in a Canaanite sample from Lebanon, 1650 BCE-1750 BCE. The reason that I'm bringing these samples up is, in my mind, while not HV1b2, since these subclades were found in ancient Levantine remains, there's no reason why HV1b2 was not present there as well (which isn't the strongest of arguments, admittedly).
Theory 2: Ancient Egyptian
The only evidence for this origin are the only ancient sample(s) of HV1b2 - which are from Egypt. From the actual study, there's only one sample, dated to the Ptolemaic period 545 BCE - 756 BCE. According to this blog (http://www.razib.com/wordpress/category/egypt/), there were two HV1b2 mummies.
Theory 3: Northern Mesopotamian
This is supported by HV1b2's position between Armenian and Assyrian branches. This origin is also supported by a study from last year (2019), which I'll link. Additionally, HV1b2 has been found in a Yezidi Kurd and an Armenian, which could support it.

Hopefully in the not too distant future, there will be more cases (ancient and modern) of HV1b2.
