I too am researching Mack's from Wisconsin. James V Mack b. 4 Ded 1954, Hillsboro, Vernon, Wisconsin, d. 4 Mar 1948 Mt. View, Santa Clara, California, m. Loretta P. Blair. I have some info from Bonnie Fimon (rcd 6/23/01) about James' brother that states his parents names are James A Mack and Cornelia Hill and siblings as: Andrew, Lonnie, Jennie, Minnie, and Edith. (unconfirmed). Any info or suggestions welcomed. Happy to share what info I have.
