My oldest known Rieke ancestor is Heinrich Rieke of Ibbenburen. His children were Catharina Elizabeth (b. 19 January 1800), Carl Heinrich (b. 17 January 1803), Johann Gerhard Heinrich (b. 13 June 1806), Anna Catharina (b. 19 July 1809, and Anna Maria Bernhardine (b. 10 June 1817). Carl Heinrich Rieke married Anna Maria Sander (b. 9 October 1797) and they had the children Bernhard Heinrich (b. 14 December 1827), Johann Heinrich (b. 11 October 1830), and Anna Maria (b. 15 May 1835). Carl Heinrich and his family emigrated from Germany to Pittsburgh, PA, USA in 1846. Bernhard Heinrich married Louisa Tetzner (b. 25 March 1835), who claimed her maiden name was Smith and was born in Hannover. I have copies of the old German documents they brought with them. Any connections?
