Here's some info that might help (might). I live in Melbourne, where my grandfather and his two brothers were born around 1920. Their father, Robert, was born around in 1899. As for his father, I'm not sure! I know that we're related to Huey (Eugene), but I'm not sure how.
I'd appreciate if you could provide any links.
p.s. There is some great info on Huey on the Commonwealth War Memorial database.
