Not to be confused with the second Agnes Foss (1942). That ship was also an ex-U.S. Army mine planter of the same name, the USAMP Col. George Armistead (MP-3) built in 1942. That ship became USS Barbican (ACM-5) and then USCGCIvy (WAGL 329) before itself being acquired by Foss Maritime as Agnes Foss.
