Oddly enough, I have probably seen the Q.A. Gillmore several times over the years in Saugatuk, but she was named the Reiss at that time and may still be, until moved.
P.s., my father, Quincy Charles Leslie, of Cheboygan, MI, now 89 YOA, observed in a printout from the NMHF web site that I made, that the Q. A. Gillmore was built in Cleveland. During the time of and after the Civil war, the Gillmore's owned quite of bit of land in the Cleveland area and Q. A. Gillmore was fairly well known, i.e. his name is imprinted on the the War Memorial in downtown Cleveland; he had commanded up to 40,000 troops in the war. So that would lend further credence to the naming of the tug after him.
The association with the Leslie family, was that my Great-Great Grandfather, Daniel Seth Leslie, a Captain in the Union army, married Quincy A. Gillmore's sister. Also, Q. A. Gillmore was married twice, the second marriage to the sister of General Braxton Bragg (maybe- my father says yes), whose name was the basis for naming Ft. Bragg, as far as I know. Although Bragg was in the Confederate Army, he was a West Point grad, as well.
The eldest family member I ever knew though, was my Great-Grandmother on my mother's side, who was born about 1880. Freaks me out now that I am older and realize how long ago that was.
