The only source commenting on Umaril's lineage is The Song of Pelinal, Vol 3 where it states he had an Ayleid mother and a divine father.
It's also stated he made a pact with Meridia to give him immortality. In game, he looks very similar to the Aurorans, but we've only seen his armor and it isn't too surprising to me with his connection to Meridia.
There's nothing stating who or what his father is.
