I do not have direct connection to Louis Guidroz and Amelia Hotard in my Guidroz files. Did find marriage record for Lucien Guidroz and Amelia Hotard, Jan. 10, 1889. Also for Louis Guidroz and Amelia Hotard. Louis born approx. 1864 and Amelia, 1868. They had a son, Louis Noe Guidroz, Mov. 29, 1888, Lockport.
Most of Guidroz's around Lockport are decendants of Etienne Guidroz.
