Hello Tom- The service history of the vessels you wish to read may be found at DANFS (Dictionary of American Navy Fighting Ships). This is a web record; internet available.

It was not uncommon for personnel to get an inter-service change during Mr. Lincoln's war as the Federal Navy grew from an April, 1861 roster comprising 79 vessels to 860 by May of 1865. I'm certain your ancestors skill were appreciated. Where did he enlist and serve while in the Army?
