If you have any open questions about the Tillaeus family I'm happy to answer them. I think you might be quite interesting about Johan Tillaeus's son Adolf Tillaeus who was appointed into the emprial court of Saint Petersburg in 1860s when he worked there as a tailor of the Tsar family. Adolf Tillaeus was born 24th February 1845 at Leppävirta and his parents were Johan Tillaeus and Lisa Nikkinen from Rantasalmi. Johan Tillaeus himself was born 9th September 1802 Rantasalmi, Vaahersalo and he died 30th November 1882 at St. Petersburg.
