Thank you kind sir: My cohort in Memphis has most likely checked that source while helping me compile documented information for 130-page booklet "That Man Named Solon", about Dr. Solon Borland who arrived in Memphis winter 1836, spending about half his adult life there splitting it with Arkansas until 1861.
She uncovered a treasure trove of information, even a trip to Holly Springs, MS, visting Walter's house where Gen Grant's wife, the slave owner Julie, resided until 20 Dec 1862 when our Capt Oliver Crosby GRAY of Co. A, 3rd Ark. Cav. Reg. under Gen Van Dorn (a regiment formed by Col. Solon Borland in 1861), and others upset Gen Grant's apple cart, sending him to your fair city, but found nothing on Fannie's tribute to Harvey Walter.
The booklet has been filed with Memphis Library/history Department's Dr. Jim Johnson, possibly found in the 'Memphis Room'.
