Since John and Josephine were not married until 1875 and she was listed as having no children in the 1900 and 1910 censuses, Ollie must be the son of a previous marriage, but I have not found a record of who John’s first wife was.

Her death certificate records Mayme Ann Prince, age 71 years 3 months 25 days, born 1 Jan 1870 in Mayview, Missouri, died 26 April 1941 in Odessa, Lafayette Co., Missouri, residence 300 Wells St., Odessa, married, wife of O. B. Prince, father Butler Moore, born in Lexington, Mo, mother’s maiden name Mollie Vaughn, birthplace unknown, cause of death pneumonia, informant Mrs. C. L. Garther, Higginsville, Mo., burial in Odessa Cemetery.

Lafayette Co. Missouri marriage books scanned online at Ancestry.com record the marriage of Ollie B. Prince of Odessa and Mamie A. Moore of Mayview on 27 Dec 1893.
