Hello. I am looking for more information on my great-great grandmother's family. The only information I have is her maiden name was Laura Dorwin. She married Louis Brooks. They lived near Nortonville, ND and had three daughters Cora, Jean, and Irene. I'm not sure who is the oldest. Cora was my great-great grandmother and is no longer with us. As far as I know, Jean and Irene are alive. All information will be appreciated. Thank you.
