The Chinese tended to come from west to east, hitting the mountainous areas. They were so good at the mountain blasting from one section of China that they kept bringing them over...Irish, including my grandfather and great-uncles were heavily involved coming west. Many groups, including African American, Slovak..I almost want to say Cuban..some group you wouldn't think of..I am not sure..anyway, I am sure there were Poles and Greeks and almost everyone you could think of who just landed on the shores of America. mg
