I am researching the family of Thomas and Lilly L. Simson of Milwaukee. Their children were James Bruce aka Jock, Pearl, Margaret, and Christine. There was a relative with them named Isidor who was VP of the Scheftels & Simson Co. James disappeared, leaving a wife and son. He was a pharmacist and was born about 1900 in Scotland. I am most interested in locating any information on him. Any help would be most appreciated. Thank you.
