Dear Pat,

You do not state in which country you are located in?
Do a search in the website of the National Archives Discovery Channel at https://discovery.nationalarchives.gov.uk/results/r?_q=TCHERNY&_sd=&_ed=&_hb= 
There are 8 files for TCHERNY, which are naturalisation files including Application files which will contain a lot of background information
about the applicant.

Do a search for TCHERNY on the following website www.freebmd.org.uk which you should find useful.

Regards,
