We are assuming that the way It is heard in in english is how they are spelling it, chep and sek/sec, like wait a second. The last name is all we have, we suspect that we may need to secure his original birth certificate if we want to get the correct spelling. Of course at this point we have no idea of places where his family comes from the in the old country. Someone said it could be cepek, not sure why an s would show up in the spelling. Thanks
