You really have not given enough information for people to try and help you. Were the sisters already married when they arrived to the US? Alone, or with children? Do you know their husbands names? If they were not married yet, what was their maiden name? I looked for example at Julie (or Julia) Simmons arrived in that time period on FamilySearch and found such a long list that there was no way for me to narrow it down. Also, they may have entered with Yiddish names and changed their names later. I suggest you start at FAmilySEarch and see if that helps you. You might find the Stephen Morse website as a help to you to link easily to the right places in FamilySearch for the various potential ports.
