perhaps I can help you...
My grand father and his parents were living in farciennes. My grand father was named René Zicot (probably born in 1916...) as my great grand father. Perhaps Adrien was my great great grand father?
my grand father had two sisters ( Marthe and Rachel) and a brother(died young and had two children: Daniel and Anne). My father is Michel Zicot born in 1943 (3 girls: Anne françoise, Emmanuelle and Catherine).
If you need precisions or corrections I can ask my grand mother who has such an exceptionnal memory of dates.
