I hope you get this because it's been quite awhile since you posted your message. My husband's great-grandpa was Joseph W. Dunnigan, his grandma was Joseph's daughter , her name is Ollie and she still is alive in California. We don't have too much on him, maybe you can tell us more if you have it. We have his picture and will share. How are you kin to him? Hope to hear form you again.
