I haven't visited this site for while, and it's interseting to learn a couple of things. My history as I know it is this. My grandfather was one of three boys. Their father was Robert George (Roy) Mehegan, who was born in 1898 or 1899. He was married to a Mary Anthony. He definitily did not have any other kids. I was told HIS father was somehow related to Eugene (Hughie) Mehegan, maybe his brother or cousin?
I did find on the war website that Eugene Daly Mehegan was the son of Robert and Mary Mehegan (the same names seem to keep popping up).
