Angel Rechmial

Does anyone know anything about this Angel/Divine Name besides it means

which signifies great and strong god of love, of grace, and mercy

That seems to be the only information I can find on him/her/it. (Do Angels have genders? What are they?)

It looks like the same bit of information on Psalm 8 has been copied and pasted everywhere I looked.

Does anyone know if the name is pronounced like Rick – My – al (soft L, like ll)

It’s pronouced “Rekh-mee-all”. I dunno if you know how kh is pronounced, german ch. Like in Akhenaten or Ankh-af-na-khonsu.
