I am trying to identify the following Japanese mon:
My research has hinted that the tortoise-shell shape may be of Shinto influence and that the triune division is a form depiction of the tomoe, but I have been unable to confirm this apart from this very similar looking mitsu-domoe kamon:
I have also found these close examples:

I am hoping someone can positively identify the mon.
The mon is on a Jingasa, a hat worn by samurai that appears to be from the late Edo period. Apparently this mon is called a Mitsu-Shikishi and I believe “Mitsu Shikishi Dai” would roughly translate as “Represents three Shikishi” (Shikishi being square traditional Japanese paper board for poetry and calligraphy). The mon certainly does look like three Shikishi squares. But I still don’t know what family or entity this represents. Maybe not a family but a military unit? My understanding is that the Ashigaru used mons to identify units or regiments.
