I just now got on this forum. My father Mordechy Kugel also born in Krinki left Krinki before the War. He and his family also went to Buenos Aires Argentina. I have some old photos from that voyage. My Uncle who I never met stayed behind, he found a woman (jewish) there and married her. My father and his father Zvi continued to Israel about a year later. That is just about all I know about that. My grand mother came to Israel a couple of years later that part of the journey is murky and I am not sure about. It is possible they all left on the same ship as it seems that the story you know and I know are the same.
