Penny, You wrote:"My names in Saginaw MI Charles W. COOK, wife Marvilla PARQUETTE COOK died in Saginaw June 16, 1885 giving birth to a daughter, Myrtle. I can not find any info on any of this. On Myrtle's marriage license it says she was born in Saginaw MI. So this is where I am researching this family." In the 1892 Saginaw & Bay County Michigan Biographies, I find a William L. Cook. His wife was Rachel Murch, whom he married on April 21, 1857. They had 4 children: Silas; Lizzie, wife of William Vance; Kittie and Charles. Of course I'm not sure this is the Charles W. Cook that you are looking for, you will need to prove or disprove this. There is a lot of other family history in the small article, giving both William and Rachel's parents and birth places. If you think this is your line, you might request a copy of either the Bay City Public Library on Center Avenue, Bay City, Michigan or the Hoyt Library in Saginaw, Michigan.
