I wonder if my great,great-grandmother is connected to your Roches. Her name was Hannah (Anne) Roche (Roache, Roach). She was born in Ireland around 1795. She was a daughter of Michael and Mary Roche. She was married to Thomas Hartnett who died in Ireland prior to Anne emigrating to Salem, MA area around 1849. Anne could have settled in IL where there were Hartnett relatives, but she chose Salem as her new home because her sister, name unknown, was living there. According to the 1860 Anne resided on Boston St. near the Peabody line. However, in 1856 she was residing in South Danvers (Peabody).
