In 1983 I met Rose Arvoy (maiden name, I forgot her married name) from Manteo NC. She was immediately interested in my last name, and we compared spellings. She told me that her family name had also been changed when the family immigrated to America, and had originally been Arvai.
At the time, I would have estimated Rose Arvoy to be about 60. I'm sorry that I do not have an further information about her whereabouts or circumstances. Good luck with your research.
