John Nicholson, b. around 1840, only hint is from a child's death certificate that he was from County Mayo. He was in the US by the 1870 Census in Brooklyn NY married to my great grandmother, Kate Burke, He was a plumber by trade. The couple married in NY but I haven't been able to find the RC record in spite of many $25 contributions to parishes in a likely area of Williamsburgh. The couple had 8 children, Mary Eugene b 1870 ( my grandmother), William b. 1872, Sarah b 1873, John b 1876, Kate b 1878, Agnes b 1881, James b 1883, Joseph b 1885. William and Sarah died on the same day in 1875 of scarlet fever. Kate died in 1880 at age 18 mos. John and Kate lived together on Grand Street in the 15th Ward from 1870 until John's death on 25 Dec 1889. Kate lived on at the same address until 1900 when she moved with her children to Van Eyck Street. In 1901 she entered the Brooklyn Home for the Aged and Infirm and died there in 1911. I am trying to find the parents in Ireland of John Nicholson and/or any siblings that may have come to NY. I have researched all the Nicholsons in Brooklyn, Kings County, who were alive at the time of John's life in Williamsburgh and have found no connections. Sheila MacAvoy Block
