I need some help >from the given name mavens. I'm working with records pulled >from the Vilnius Central Archives. I see my relative's name listed as Jesna, Sija, Sije and Hansejas. I'm sure they are all the same person. I know the name translates to Joshua. I see his wife listed as Chase and Chasta. Her official name was Glel.
What is the significance of all these forms of the name? Where do they come from?
Is "Rause" in Base Rause, part of the given name? I've consulted Gorr's "Jewish Personal Names" but it hasn't been much help.
