Newt Gingrich is Not Croatian-American == 
 Newt Gingrich has absolutely no Croatian ancestry. His father's last name is McPherson and his mother's maiden name is Daughtery. Newt's stepfather is Gingrich, who possibly is Croatian, but Newt has no Croatian heritage. According to his family history, the only Europeans were from Scotland, Switzerland and Germany. See this link for his family history:     
 :Maybe he identifies with the ancestry of his stepfather. Ancestry is a matter of choice and not always bloodlines.     
 There is no information available on Gingrich's last name or his stepfather being Croatian, but because it ends in -ich I wrote "possibly". Based on online information, the last name "Gingrich" appears to be of Swiss German origins ().
