My great grandfather,Peter Yunker emigrated to Canada via New York in 1886 on the Aller.I don't know the shipping line yet as I've just begun to work on my family's history. The original spelling was Junker and the J changed to Y after arrival in Canada. He emigrated with his wife Lucie and 7 children, three more were born in Canada. The oldest sons, Joseph,Peter and Max I believe left Canada and went to the west coast of USA. Don't know anything more about those who left Canada. Hope this is useful to you.
