From checking ancestry.com I found information that Idabell's mother was probably Blanche West Morsaw who married a William Morsaw after being married on November 29, 1924 to a Mike West and they divorced on January 31, 1927 in Muskegon, MI. She then married William Morsaw on March 26, 1927 in Muskegon, MI. Mike West was born in Mexico and his parents were listed as Antonio West and Yelles Salsido as shown on the marriage record of Mike West and Blanch Lewis. ( I have not found any information on Mike West as to when he died or where he is buried. I did find him in the 1930 Census. I did find where they had another Child, Delores West who died in infancy, Death information shown below) Also added his marriage record to Blanche Lewis
