I am the Great-Granddaughter of Joseph O'Hanlon who served as the Fire Chief of New York city in the early 1900's. He had three sons, Herbert, Reese, and Frank (I believe). I am the granddaughter of Herbert O'Hanlon. I don't know much about my heritage as my Grandfather, Herbert, died from cancer in October, 1978. I was born in 1980. I know that I have an ancestor named Count Redmond O'Hanlon, but that is about it. I would like all the information I can get about the family as far back as recorded. Thank you!
