My grandmothers name was Sarah "Sadie" Michael Kobseff (d. 04Feb 2001) She had the following siblings: Emily Marionetti, Nellie Shubin, William "Bill" Kobseff, Nick Kobseff and George Kobseff. Her fathers name was Michael Ivan Kobseff who immigrated from Russia in 1910 with his wife Masha Gregory Samaduroff. I believe Michael Kobseff's mothers maiden name was Patapoff and that is where I hit a dead end as I believe further family records are all in Russia. Any information on any family member would be greatly helpful.
