The name Vadetsky-Vides occurs only once in a revision list in the shtetl Malat(Moletai) in 1834.  My GGGgrandfathe Movsha is married to Aron Vadetsky-Vides' daughter. 
In subsequent records I find no one with this hyphenated name.  I find Vadetsky's, Videtsky' and Vides.  Anyone have an idea of what happened?  Other members of the family married Malatskys who were from Vidzy?  Could that be a connection.  I welcome any conjecture or facts..
