This Frederick Hilburn was the son of Woodward A. Hilburn/Hilbun and is found with his father on the 1850 Pontotoc co., MS census. He later moved to Desoto Co., MS and I found his will at the MS Dept of Archives and History in Jackson (on microfilm). The following is my transcription of his will.

The last will & Testament of one F. A. Hilburn being of sound mind but knowing the uncertainty of human affairs knowing that life is short & death certain I hereby direct that after my death all my just debts & funeral expenses be paid that my personality be first exhausted to the payment of any debts & if there be not sufficient therefore that my plantation on which I now reside be rented leased or cultivated as to my executors may seem best & the profits arising therefrom be appropriated to the payment of my said debts & after the same? Sti all? Have been thus paid I .. that my plantation be continued to be cultivated directed or rented as to my executors may seem best & that the profits arising there from be appropriated to the maintenance of my two daughters Susan F. Hilburn & Sarah A. M. Webster until they shall marry & to the education & maintenance of my three sons Andrew J. Hilbun, Fredrick A. Hilbun & Samuel (or Lemuel) T. Hilburn until they respectively attain the age of 21 years & that after my youngest son attains age 21 or in case of his death then when my next youngest son attains the age of 21 I will & direct that all my property hath seal in his presence & the presence of each other & at his request have herewith set & subscribed our names & seals this the 9th day of November 1872.

**An interesting sidenote: many of the descendants of F.A. & his siblings moved to TX & some to CA. Most of them spell their name HILBUN.
