Hello, Mr. Frazier- You have your Whittles scrambled. There were two of em', father and son. Both CSN officers and both named William. The 1840 birth date you mention is for William, Jr. who served on the Nashville and the Shenandoah.
William, Sr. was entered into this world in 1805 and departed in 1878. His rank of Commodore given November, 1861 when he took command of supply for District 1 at the naval base in New Orleans. He shuffled out of town on the five o' clock train on April, 28, 1862 with Lovell and the rest of them. He held various positions in Intelligence, Ordnance and Logistics throughout the war. His age and the affects of a wound sustained on a beach in Mexico prevented him from combat command.
Your correct about the linage. Now hear this. On the most exaulted of thrones you are seated on nothing more then your own ass.
Pleased to have Prof. Harris tie this tome together for print and look foward to purchasing it.
Regards Henry E. Whittle
