My muses' fathers.... require headcanon and guesswork. /raises eyebrows at Capcom/

We have virtually no background on Wesker's bio parents, outside of them being highly intelligent.

Oswell Spencer does not count as a father, maybe as a guardian at best.

We know Ethan came from East Texas, and lived in California, so safe to assume his family might have come from Texas and moved to Cali at some point.
