Greg,I am the daughter of William Robert Hoffart(born 1939 in Euclid,Ohio.I was told that the spelling of Hoffart vs. Hrovat came about when my great-grandfather(Louis Ludwig Hrovat) and his brother(frank?) arrived in the United States (got off the boat,as the saying goes).They more than likely said their name with a heavy accent. Rovat(with a long o)sounded like Ho fart. Doing some research,it seems that the names:Smith,Jones,etc. were given to people when the authorities could not understand the immigrants. Your grandfather(my great-grandfathere) kept the spelling as Hoffart.I have a copy of his brother's naturalization papers from 1936(?) saying he changed his spelling to Hoffert as part of the process.For business purposes your father and Uncle also changed their spellings.Really who wanted to go around with all the taunting, like I did as a child.Example=who farts,we fart,we all fart for HO Fart. My grandfather (William Ferdinard Hoffart)...also said he was slovenian/german.My 2nd cousin,Louis, has told me some "interesting" stories that he learned about the family history in Europe,I won't go into that now. They may have been born in Austria,but educated in Germany.
