I suppose it's possible that another family of Dubersteins from Minsk could have been sailing over with the same number and gender mix of children, with names that correspond as well to ours. But not too likely...

So I'm assuming that:

Moses = Morris

Mere = Mary

Chane = Anne

Breine = Bertha

Jankno = Jacob

Judel = Julius

Dobe = Debbie

Cive = Ceil

Michle = Mabel

Gedalye = Gerald
