If Miriam Rolnicki was the girl who signed the album (and not Mirjam Rolnicka), then this information is correct. Until we know for sure, I am marking this as "possible."
Also, based on secondary sources, we can surmise that it is likely that Miriam was deported to Chelmno since there were regular transports from the ghetto to Chelmno from February 22-28, 1942.
