Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

i am new at this forum and i wanted to tell the above member that "Czop" is my maiden last name. But around 1950's my grandparents decided to change to spelling for reasons due to moving to USA.."americanise" it, for lack of better word! The spelling went to "Tchop", the "t" is silent.
