Pablo, I am Cindy Brunner -- daughter of Lloyd, son of Edward, son of John, brother of Gottfried and Anna. I cannot answer your question. I don't know if Anna was married. The only fact I know with certainty is that Anna Brunner was with her father and siblings on the steamship Galicia when it arrived in Chile from Switzerland on 28 December 1886.
Chile Civil Registry records list a marriage of Cristiano Reinike to Ana Brunner Regelipel. A record on MyHeritage for Anna Brunner Regeltepl lists her birth date as 24 February 1872 in Switzerland and her death date as 9 July 1912 in Quillem. I want to know whether that Ana Brunner was the sister of Gottfried and John.
