My fourth great-grandfather was a Tsalko (aka Tsalel). The surname was Grosbard (aka Gruonbort aka "Krudzdbert"). He was born between about 1770 and 1773; according to the 1816 Revision List, he was living in Vilkija, Lithuania in 1816. So there was at least one Tsalko in Lithuania prior to your person who was born there in 1842. -- Erika Gottfried Teaneck, New Jersey
