The names Francesco and Mercurio Moceri do not sound familar to me. However, there is a possibility that Francesco and my Giuseppe could be brothers, but at this time I really do not know. My Giuseppe's wife, Fara, was born around 1849, so I'm guessing Giuseppe was born somewhere around the 1840's to 1850's. One of their son's named Giuseppe was born abt.1869,and he came to Detroit,MI in the late 1890's. Fara came to Detroit in 1913 when she was 64 years old and a widow.
