NO, immigration officer changed the spelling of your ancestor's surname. The manifests were written at the port of departure from a record that our ancestor presented to the shipping clerk. Yes, transcribing mistakes happened at the port of departure but much more at the port of arrival when the manifests were being transcribed. Need to keep in mind that Europeans do write few letters differently from Americans.
