My g grandmother's maiden name was Addison.Her full name was Elizabeth Victoria Addison.She was the daughter of William Eugene Addison and Mary Elizabeth Judd , and was born inAlabama ,but lived most of her life in Natchitoches Parrish and died in Natchitoches in 1939.She is buried in the old Fern Park Cemetery there. She married William Robert Shehane.My grandmother, her daughter,whose name was Rose Ellen Shehane , was cousin to a Dr. Addison who lived in the Robeline and Many ,La. areas.This may be your Dr. John Addison. I remember my Mother speaking often of "Dr. Addison" ,if indeed he is the one you refer to. I have been searching everywhere for information on these Addisons, but have found virtually nothing on William Eugene and Mary Eliz. Judd.I would appreciate any information you could share with me.Thanks.
