For the purpose of connecting actor Mandy Patinkin, it would be helpful to know the relationship between Louis and David Gubersky, who immigrated to the US from Russia on the same day in 1892. In FamilySearch their profiles show as sons of Abram and Sora Gubezski of Vilnius but there isn't any documentation that clearly supports this.
Any help with determining the exact nature of the relationship (if any although some kind of relationship seems likely) between Louis and David would be appreciated.
