I'm looking for any information on my great-grandfather's family. His name was Nicola Angelo and he was born in southern Italy, possibly near either Naples or Chieti around 1890. His family immigrated to Allegheny County Pennsylvania when he was young. He usually went by Nicholas, and by the time he was married he had changed his name to Harry Miller. His wife's name was Jennie, and his children were Vincent, James, Margaret, and Nicholas. He had three brothers, Lawrence, Tony, and Thomas. His parents went by Jean and Mary. If anyone has any information it would be greatly appreciated. Thank you.
