Earl,

Try searching The JewishGen Ukraine Database
https://www.jewishgen.org/databases/Ukraine/

I suggest doing a soundex (sounds like) search.  I very quick look at the database shows a few people named Tsoglin from Chernigov.  Surname also spelled TSOHLIN.  Other spellings show up, but you'll have to figure out if they are relevant to your family, or not.

Regards,
