Augustus Merrillac (also called Augustus Marrilar, Augustus Merrilac, Augustus Murilac, A. Murilao) was mustered into service as a “Seaman” November 27th, 1861 with Captain Henry Mulrenan’s Florida Volunteer Coast Guards. He remained in this unit until mustered into Confederate service on April 25th, 1862 when was enlisted as a 3rd Corporal in Captain Smith’s Company (Key West Avengers), 7th Regiment Florida Infantry by Major R. B. Thomas at Tampa, Florida for a period of 3 years or the war.
He is reported present for the period March 25th, 1862 through June 1862 and due $50 bounty and clothing money. On the Company Muster Roll for April 30th to November 14th, 1862, he is documented as being absent (time, pace, date, and reason illegible are illegible). Undated Company Muster Roll for February 7 - 28, 1863, he is reported absent on parole since December 1st, 1862 at Tampa, Florida. (Owing to the large number of men documented as being left behind sick when General E. K. Smith withdrew from Kentucky in the fall of 1862, it is not unlikely that Merrillac was among these).
He is reported present on all further muster rolls through February, 1864. He was transferred to the C.S. Navy on February 24th, 1864. There is no further record of service after this date.
