Hi! If you want to find out more about the Taiclet, you can check the online resources at LISA90. It is the online archives and database for the Delle/Belfort area. http://www.lisa90.org/lisa1/pages1/accueil.html
In Delle, you can find a "Piecquet" and "Pieque" family. Same pronunciation.
There is a Francois Joseph Piguet in Giromagny, a few kilometers away in 1817.
Hope this helps!
