I have hit a brick wall on my father's father.
John Wilson said he was born in 1883 in Oregon, however the Australian citizenship papers, submitted in 1940, said he was born in Dallas Texas. John came to Australia in about 1910.
John appeared to speak Italian reasonably fluently to the Banana pickers in NSW.
He never mentioned his family to any of his kids.
We have no leads as to his background or family in the USA
