I am NOT from the Mitchells who were in the American Colonies in the 1600s.We are 19th century Irish.
I have a Robert Mitchell (b. 1862/1865 in County Armagh, Ireland), son of William Mitchell of Aughnamullen, County Armagh, Ireland and his wife, Agnes Harrison of County Monaghan, Ireland.William and Agnes immigrated to Smithville then Greene, Chenango County, New York; I was told coming 1865, but census says 1881, though they were in 1880 census.Then between 1920 and 1930 widowed Robert and some of his children moved to NOrth Hempstead.
I am following his children.For example, I was unable to follow two of the girls.Whom did they marry?
Mary A. Mitchell (b. 1891)
Agnes M. Mitchell (b. 1892)
Can you conform taht Madeline married Murtaugh adn this was she in the 1930 census?Her hausband, the head of the household, calls her father and brother boarders rather than father-in-law and brother-in-law.
I am also interested in following the families of William's brothers and sisters, but lost track of married girls and boys with common first names:
Bessie A. Mitchell (b. 1861)
John Mitchell (b. 1870) There are lots of them.
Joseph Mitchell (b. 1877)
