Albert Marth discovered NGC 4056 = m 229, along with NGC 4042 and 4046, on 18 Mar 1865. All of these objects have uncertain identifications because of imprecise positions and several faint nearby galaxies. His description "eF, vS" adds no new information. RNGC identifies PGC 38140 as NGC 4056. This galaxy is located 12 tsec of RA east and 2.6' north of Marth's position. If m 230 = NGC 4060 = CGCG 128-006 then the declination errors are similar. Although this galaxy is extremely faint, Marth could have picked it up with Lassell's 48-inch. See Harold Corwin's identification notes.

600/800mm - 24" (3/22/14): extremely faint and small, round, 6"-8" diameter. At 375x, I could repeatedly glimpse this galaxy, though would not have picked it up without knowing the exact location. Located 3.5' SW of NGC 4066 in the NGC 4065 cluster.
